A capacitor of capacitance `C` is charged to a potential difference `V` from a cell and then disconnected from it. A charge `+Q` is now given to its positive plate. The potential difference across the capacitor is now.

Options

A. ` V`
B. ` V+(Q)/(c )`
C. ` V+( Q)/(2C)`
D. ` V-( Q)/(c ) , `if V ` lt ` CV

Answer

C
