Question

A parallel plate air capacitor is made using two plates of area 0.2 m2 separated by 1 cm. It is connected to a 50 V battery. What is the charge on each plate?
Options
A 2.85 nC
B 9.15 nC
C 8.85 nC
Correct Answer
D 2.05 nC
Correct Answer

Option C is the correct answer.

Detailed Explanation

C = eps0 A/d = (8.85x10-12)(0.2)/(0.01) = 1.77x10-10 F. Q = CV = 8.85 nC.

Hint

C = eps0 A/d = (8.85x10-12)(0.2)/(0.01) = 1.77x10-10 F.
