Consider the charged cylindrical capacitor. The magnitude of electric field E in its annual region
A
varies as 
, where r is the distance from its axis.
, where r is the distance from its axis. B
is zero.
C
is same throughout and 
.
. D
varies as 
, where 
is the distance from its axis.
, where is the distance from its axis.
Text Solution
Verified by ExpertsThe correct answer is:
A
From Gauss's law 
where, E = electric field, 
surface area 
free space permittivity
where, λ = charge per
unit length,
and r = distance from
axis of cylinder.
