What is electric field intensity at a point at a distance r meter from q coulomb of a charge in free space ?

A

`1.125xx10^(9)V//m`

B

`2.125xx10^(9)V//m`

C

`1.525xx10^(9)V//m`

D

`2.525xx10^(9)V//m`

Text Solution

Verified by Experts

The correct Answer is:
A
`E=i/(4piin_(0))xxq/r^(2)`
`therefore" " E= (9xx10^(9)xx5xx10^(-3))/0.04=1.125xx10^(9)V//m`
