Important Questions of Electrostatics for Board Exam Class XII

electrostatic conceptual questions

The comb rubbed on dry hair attract small pieces of papers and this process is due to a Paper is a good conductor b paper is an insulator c both a and b d None of these. A test charge q is moved without acceleration from A to C along the path from A to B and then from B to C in electric field E as shown in the figure. Question 4: Why do electric field lines can never cross each other? This site offers information needed to understand the operation and maintenance of Van de Graaff generators. So sensitive electric instruments can be saved from external electric fields by covering them with hollow conductor. In which point the hollow sphere does never produce an electric field? A great visualization of the Coulomb force in action. Remember to convert distances to meters and charge magnitudes to Coulombs so the units work out and you are not off by any factors of. Addition of voltages as numbers gives the voltage due to a combination of point charges, whereas addition of individual fields as vectors gives the total electric field.

This tutorial helps students understand this relationship. The shape of equipotential surface due to i line charge is cylindrical. Potential inside a shell is constant. Accompanied by detailed background information, this lesson promotes conceptual understanding of electron transfer. Electrons in the conductor are forced induced to move about the sphere, as they are repelled by a negatively-charged tube. If we put A closer to the first electroscope and touch C to the sphere of second electroscope, find the type of charge electroscopes have.

Graph the electric potential V with distance r due to a point charge Q. Notice that the vector arrows are of equal length force magnitudes are equal and in different directions. In one of the classic nuclear physics experiments at the beginning of the 20th century, an alpha particle was accelerated toward a gold nucleus, and its path was substantially deflected by the Coulomb interaction. In this game-like environment, students place positive and negative charges on a simulated ice field. Your students will have fun moving charges around to investigate interaction of charged particles and watch as electric field lines are generated.

Also, the line integral of electric field from initial position A to final position B along any path is termed as potential difference between two points in an electric field, i. Define the term potential energy for charge q at a distance r in an external field. A dipole with its charge -q and +q located at the points 0, — b,0 and 0,+ 5,0 is present in a uniform electric field E. If Varsity Tutors takes action in response to an Infringement Notice, it will make a good faith attempt to contact the party that made such content available by means of the most recent email address, if any, provided by such party to Varsity Tutors. The worksheets offer them structured guidance.

It gives explicit directions for set-up, plus open-ended questions to help kids explore charge interactions. Then K 1 is opened and K 2 is closed order is important. Give reasons, ii Two charges + q and — q are located at points A 0, 0, — 2 and B 0, 0, 2 respectively. Both the red vector arrow and the blue vector arrow have magnitudes of. The equipotential surfaces of this field are planes parallel to the Y Z-plane. How does the work done compare in the two cases? Is the work done by the field is moving a small positive charge from Q to P positive or negative?.

Effect of dielectric on capacitors 5. Assume that they have a triangle configuration with side length of the order of 10 —15 m. A: Key K is kept closed and plates of capacitors are moved apart using insulating handle. Draw three equipotential surfaces corresponding to a field that uniformly increases in magnitude but remains constant along Z-direction. How much work is done in moving a test charge from point P{7, 0, 0 to Q - 3, 0, 0? Choose the correct option s. The lesson integrates the game with free-body diagrams and vector addition.

Conceptual Physics: Electricity

electrostatic conceptual questions

During a thunderstorm, separation of charge produces enormous electrical potential both within the cloud and between the cloud and ground. Key takeaways: 1 Opposite charges attract and like charges repel; 2 Magnitude of force is related to quantity of charge and distance between the interacting objects; and 3 Newton's Third Law is applicable to electrostatic forces. So initially before the charge is given What will be the masses after the charging? Electric field inside the hollow spherical charged conductor is zero. So, electrostatic potential is a constant. The potential due to a dipole at any point on equatorial line is zero, not an axial line.

For the diagram given as below, potential difference between points A and B will be same for any path. What is the potential energy of this charge configuration? Then, what will be the electric force between them a 5N b 5 dyne c Zero d None of these 12. Many students have difficulty understanding the interactions that cause an electric force between charges. Inverse relationships are common in nature. It helps if they begin their investigation with a very simple 1-D representation of the electric force that one particle exerts on another.

Derive an expression for the electric potential at any point along the axial line of an electric dipole. The induction process can be confusing to students, and this Physics Classroom tutorial does a terrific job of making it clear. Note: This model is available only in Java at this time. When a positive charge is placed in an electric field, it experiences a force which drives it from points of higher potential to the points of lower potential. One of the blocks has thickness d 1 and dielectric constant k 1 and the other has thickness d 2 and dielectric constant k 2 as shown in Fig.
