The magnitude of electric field vecE in ...

The magnitude of electric field `vecE` in the annular region of a charged cylindrical capacitor.

A

is same near the outer cylinder then near the inner cylinder

B

is higher near the outer cylinder than near the inner cylinder

C

varies as `1//r` where r is the distance from the axis

D

varies as `1//r^(2)` where r is the distance from the axis

Text Solution

Verified by Experts

The correct Answer is:
C
The magnitude of electric field at a distance r from the axis is given as
`E=(lambda)/(2piepsilon_0r)ie.Eprop1/x`
Here `lambda` is the charge per unit length of the capacitor
