The electric field intensity at a point ...

The electric field intensity at a point 20 cm away from a charge of `2 xx 10^(-5)` C is

A

`4.5 xx 10^(6) NC^(-1)`

B

`3.5 xx 10^(5) NC^(-1)`

C

`3.5 xx 10^(6) NC^(-1)`

D

`4.5 xx 10^(5) NC^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
`E = (q)/(4 pi epsilon_(0) r^(2)) = (9xx 10^(4) xx 2 xx 10^(-5))/((0.2)^(2)) = 4.5 xx 10^(6) NC^(-1)`
