Two identical metal plates are given positive charges `Q_1 and Q_2`(ltQ_1),` respectively. If they are brought close together to form a parallel to form a parallel plate capacitor with capacitance C, the potential difference between them will be

A

`(q_(1)-q_(2))/(2C)`

B

`(q_(1)-q_(2))/( C)`

C

`(q_(1)-q_(2))/(4 C )`

D

`(2(q_(1)-q_(2)))/ ( C)`

Text Solution

Verified by Experts

Answer (1)
Inner plates accumulate equal and opposite charge `Q=(q_(1)-q_(2))/(2)` and that actually makes the capacitor Now `V=(Q)/(C )`.
