Question

A parallel plate capacitor has an electric field of 10⁵ V/m between the plates. If the charge on the capacitor plate is 1mC, the force on each capacitor plate is –

• A. 0.5 N
• B. 0.05 N
• C. 0.005 N
• D. None of these

Answer 1

Answer: (B)

0.05 N

Answer 2

Force between plates

F =

F = = $\frac { 10 ^ { - 6 } \times 10 ^ { 5 } } { 2 }$ = .05 N

Electric fled E =
