A test charge q is made to move in the electric field of a point charge Q along two different closed paths. Fig. First path has sections along and perpendicular loop of the same area as the first loop. How does the work done compare in the two cases?

A point charge q is rotated along a circle in the electric field generated by anotherj point charge Q. The work done by the electric field on the rotatin charge in one complete revolution is

A point charge Q is moved along a ciruclar path around another fixed point charge. The work done is zero

How much work is done in moving a charge of 5C across two points having a potential difference of 16V?

In the electric field of a point charge ( + q) , placed at the centre of a circle , a certain test charge is carried from point A to B, C,D and E Least amount of work is done along the path

Plot a graph comparing the variation of potential ‘V’ and electric field ‘E’ due to a point charge ‘Q’ as a function of distance r from point charge (ii) Find the ratio of the potential differences that must be applied across the parallel and the series combination of two identical capacitors so that the energy stored, in the two cases, becomes the same.

How much work is done in moving a charge of 2 C across two points having a potential difference of 12 V ?

An isolated conducting sheet of area A and carrying a charge Q is placed in a uniform electric field E, such that the electric field is perpendicular to the sheet and covers all the sheet. Find out the charges appearing on its two surfaces.
