A charge of +1 C is placed at the centre of a spherical shell of radius 10 cm. what will be the work done in moving a charge of +1muC on its surface through a distance of 5 cm?

Two point charges equal to +10muC and +20muC are 1 m apart. What is the amount of work done to bring them clsoer to each other by 50 cm.

Two points charges +10muC and -10muC are separated by a distance of 40 cm in air. How much work is required to separated the two charges infinitely away from each other?

Two small charged metal sphere A and B are situated in a vaccum. The distance between the centres of the spheres is 12.0 cm, as shown in the fig. The charge on each sphere may be assumed to be a point charge at the centre of the sphere. Point P is a movable point that lies on the line joining the centres of the sphere and is distance x fromt he centre of sphere A. The variation with distance x fo the electric field strength E at point P as shown in the figure. Use fig to state and explain the distance x at which the rate of change of potential with distance is maximum and minimum.
