Electric Charges and Fields

Question:

A positive charge (+q) is located at the centre of a circle as shown in figure. W1 is the work done in taking a unit positive charge from A to B and W2 is the work done in taking the same charge from A to C. Then.

                       

Options:

W1 > W2 

 W1 < W2

 W1 = W2= 0

None of the above 

Correct Answer:

 W1 = W2= 0

Explanation:

Point A, B and C are at the same distance from charge +q; hence electrical potential is the same at these points, i.e.  There is no potential difference between A, B and C. Hence W1 = W2 = 0.
