A cylinder of radius r and length l is placed in a uniform electric field of intensity E acting parallel to the axis of the cylinder. The total flux over curved surface area is

A

`2pi r E`

B

`((2pi)/(l))E`

C

`2pi r l E`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
D

Total flux emerging from the curved surface of the cylinder,
`phi = E.ds = Eds cos theta`
Here, `theta = 90^(@)`
`phi = E ds cos 90^(@)`
`phi = 0`
