The electric field on two sides of a thin sheet of charge is shown in the figure. The charge density on the sheet is

A

`2epsilon_0`

B

`4epsilon_0`

C

`10epsilon_0`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
B
Let `E` be the external field (toward right). The
`E-sigma/(2epsilon_0) =8`………….i
`E+sigma/(2epsilon_0=12`………..ii
Solving these equations we get `sigma=4epsilon_0`
