Two infinitely long parallel conducting ...

Two infinitely long parallel conducting plates having surface charge densities `+ sigma` and `-sigma` respectively, are separated by a small distance. The medium between the plates is vacuum. If `epsilon_(0)` is the dielectric permittivity of vacuum, then the electric field in the region between the plates is

A

`sigma//epsilon_0` towards the positively charged plane

B

`sigma//epsilon_0` towards the negatively charged plane

C

`sigma//(2epsilon_0)` towards the positively charged plane

D

0 and towards any direction

Text Solution

Verified by Experts

The correct Answer is:
B
`E_A = sigma/(epsilon_0)` (towards -ve plate)
