Answer 1

1. False. Equipotential lines are circular only for isolated charges. When more charges are present the electric field changes and hence equipotential lines don't remain circular.

2. True. As electric field travels from positive to negative charge, the field lines converge at the negative charge.

3. False. equipotential lines are circular for isolated charges.

4. False. As electric field travels from positive to negative charge, the field lines diverge from the negative charge.

5. True. This is because if we move at an angle of 90° to the electric field, the potential energy remains the same and hence it represents the path of an equipotential line.

6. True. Electric field lines originate from the positive charge and terminate at the negative charge.

7. False. equipotential lines are circular for isolated charges.
8. True. At the midpoint between the two charges the potential due to the two charges will cancel out and will be zero.

9.True. Electric potential is inversely proportional to the distance from the charge.

10. False. One nano coulomb is 1000,000,000th of a coulomb.
