Question
The magnitude of electric field 
in the angular region of a charged cylinderical capacitor
in the angular region of a charged cylinderical capacitor Options
A.is same throughout
B.is higher near the outer cylinder than near the inner cylinder
C.varies 1/r where r is the distance from the axis
D.varies 1/r2 where r is the distance from the axis
Solution
The magnitude of electric field at a distance r from the axis is given as :
i.e.,
Here λ is the charge per unit length of the capacitors.
