Two plates are at potentials `-10 V` and `+30 V`. If the separation between the plates be `2 cm`. The electric filed between them is

A

`2000 V//m`

B

`1000 V//m`

C

`500 V//m`

D

`3000 V//m`

Text Solution

Verified by Experts

The correct Answer is:
A
`E = (V)/(d) = (30 -(-10))/((2 xx 10^(-2))) = 2000 V//m`
