A capacitor of capacitance `10 mu F` is charged to a potential `50 V` with a battery. The battery is now disconnected and an additional charge `200 mu C` is given to the positive plate of the capacitor. The potential difference across the capacitor will be.

A

50V

B

80V

C

100V

D

60V

Text Solution

Verified by Experts

The correct Answer is:
D
`9. q_(0)=CV=500muC`
`(700-q)/(2A in_(0))+(q)/(2Ain_(0))+(500-q)/(2A in_(0))=(q)/(2A in_(0))`
`q=600 muC, DeltaV=(q)/(C )=60V`
