The electric field near a conducting surface having a uniform surface charge density `sigma` is given by

A

`sigma//epsilon_(0)`

B

`sigma//2epsilon_(0)`

C

`sigma//epsilon_(0)r`

D

`sigma//2epsilon_(0)r`

Text Solution

Verified by Experts

The correct Answer is:
A
`Exx4 pi r^(2)=q/(epsilon_(0)), E=q/(4pi epsilon_(0)r^(2))=(sigma)/(epsilon_(0))`
