|
|
22.5 V
|
|
|
15 V
|
|
|
5 V

Explanation:
Detailed explanation-1: -Electric potential at a point in an electric field is defined as the work done in moving a unit positive charge from infinity to that point.
Detailed explanation-2: -A charge of 10 C is brought from infinity to a point near a charged body and in this process, 200 J of work is done.
Detailed explanation-3: -Remember to explain how work is done in a conservative field independent of the path taken. Then move to explain the electric potential and the work is done in an electric field. Then use the equation $W = qV$ to calculate the work done.
