A hollow spherical conductor of radius 2...

A hollow spherical conductor of radius 2 cm is electrifled with 20 statC. Determine the surface density of charge on the external surface of the conductor.

Text Solution

Verified by Experts

Surface density of charge of a spherical conductor,
`sigma=Q/(4pir^2)` Q = charge on the surface of the sphere, T = radius of the sphere
Here, Q = 20 statC, r = 2 cm
`therefore sigma = 20/(4pi(2)^2) `=0.398 statC . `cm^(-2)`
