2. Electric Potential and Capacitance

easy

Two plates are at potentials $-10\, V$ and $+30\, V$. If the separation between the plates be $2\, cm$. The electric field between them is.......$V/m$

A

$2000$

B

$1000$

C

$500$

D

$3000$

Solution

(a) $E = \frac{V}{d} = \frac{{30 – (\, – \,10)}}{{(2 \times {{10}^{ – 2}})}} = 2000\,V/m.$
