A small positively charged ball of mass is suspended by a long insulating thread of negligible mass. Other positively charged small ball is moved very slowly from a large distance (along horizontal direction) until it is at original position A of first ball. As a result the first ball rises by h to position B such that . Choose the correct statement (s)
Options
- AElectrostatic energy of system of charges is 2 mgh .
- BTotal work done on system to bring two balls in their final position is mgh.
- CTotal work done on the system to bring two balls in their final position is 3 mgh .
- DWork done on system to bring two balls in their final position does not depend on the magnitude of charges explicitly.
Correct answer
D. Work done on system to bring two balls in their final position does not depend on the magnitude of charges explicitly.
