1. According to the diagram, the equipotential points are _____. The arrows are the direction of the electric field.
2. If A and B are two equipotential surfaces around a positive point charge q, what will happen if we place another point charge +Q between A and B?
3. A charge q is placed at the center of a circle and B, C are the points on the circle. Another charge q is moved from A to B and from A to C. Which of them is correct?
4. What will be the nature of equipotential surfaces due to a point charge, situated at infinity?
5. What is the nature of equipotential surfaces in case of a positive point charge?
6. A charge q is placed on an equipotential surface and electric field intensity at that place is E. What is the work done to move the charge by a distance x on the surface?
7. Which of the following statements is correct?
8. A smaller sphere has potential 50V and a larger sphere has potential 100V. How should they be placed so that if they are connected with the help of a wire, the charge will flow from the smaller sphere to the larger sphere? Both the spheres are conducting and hollow.
9. An electric field is directed along the tangent of an equipotential surface.
