A conductor of capacity 2muF is charged ...

A conductor of capacity `2muF` is charged to a potential of 200 V. If an additional charge of `-2xx10^(-4)C` is deposited on it, then resultant potential will be

A

110 V

B

100 V

C

200 V

D

220 V

Text Solution

Verified by Experts

The correct Answer is:
B
`Q=CV=2xx10^(-6)xx200=4xx10^(-4)C`
`V^(1)=Q^(1)/C=(4xx10^(-4)-2xx10^(-4))/(2xx10^(-6))=100V.`
