Question 340: Electrostatics & Capacitance

Question

A parallel plate capacitor with plates of area 1 m
2
each, are at a separation of 0.1 m. If the electric field between the plates is 100 N/C, the magnitude of charge on each plate is :
(Take $$\varepsilon $$

= 8.85 $$ 	imes $$ 10
$$-$$12
$${{{C^2}} \over {N - {m^2}}}$$)

Accepted Answer

$$E = {\sigma  \over {{ \in _0}}} = {Q \over {A\,{ \in _0}}}$$
Q = AE$$ \in $$
