Question

A parallel plate capacitor has an electric field of 105 V / m between the plates. If the charge on the capacitor plate is 1 μ C, the force on each capacitor plate is (A) 0.5 N (B) 0.05 N (C) 0.005 N (D) None of these

Tardigrade Admin · Accepted Answer

Force on each plate, F=(q E/2) =(1 × 10-6 × 105/2)=(10-1/2) =0.05 N

Q. A parallel plate capacitor has an electric field of $1 0^{5} V / m$ between the plates. If the charge on the capacitor plate is $1 μ C$ , the force on each capacitor plate is

$0.5 N$

$0.05 N$

$0.005 N$

None of these

Force on each plate, $F = \frac{qE}{2}$
$= \frac{1 \times 1 0 ^{- 6} \times 1 0 ^{5}}{2} = \frac{1 0 ^{- 1}}{2}$
$= 0.05 N$
