In figure, a cone lies in a uniform electric field `E`. Determine the electric flux entering the cone.
.

A

`(ERh)/2`

B

0

C

`2ERh`

D

`Erh`

Text Solution

Verified by Experts

The correct Answer is:
D
Effective area of the cone through which flux passes is

`A = 2[1/2Rh] = Rh`
`Flux phi = EA = Erh`.
