A hollow conducting sphere of radius 1 m...

A hollow conducting sphere of radius 1 m contains `2 xx 10^(-9) C` charge uniformly distributed over the surface. Find the value of potential at a distance 0.5 m from the centre of the sphere.

Text Solution

Verified by Experts

Here, radius of sphere, r = 1 m Charge on sphere, `q=2 xx 10^(-9) C`
`therefore` Potential at the distance of 0.5 m = Potential at the surface of sphere
`therefore V = q/(4piepsilon_(0)r) = ((9 xx 10^(9)) xx (2 xx 10^(-9)))/1 = 18 V`
