The electric intensity due to a uniformly charged infinite cylinder of radius `R` , at a distance `r(gt R)` , from its axis is proportional to

A

Directly proportional to `r^2`

B

Directly proportional to `r^3`

C

Inversely proportional to r

D

Inversely proportional to `r^2`

Text Solution

Verified by Experts

The correct Answer is:
C
`ointE.ds =(ql)/(epsilon_0)implies E xx2pirl= (ql)/(epsilon_0)`
`E = q/(2piepsilon_0r) , E prop 1/r`
