Question

A parallel plate capacitor has circular
plates of radius 8 cm and plate separation
Imm. What will be the charge on the
plates if a potential difference of 100 V
is applied?
(A) 1.78 x 10-C
(B) 1.78 x 10-50
(C) 4.3 x 10°C (D) 2 x 10°C​

Answer 1

Answer:

q=CV

C of circular plate is=πr²×epsilon not/d

1/9×10⁹×1/4×64×.0001/.001

q=1.78×1/10⁸C
