A spherical conductor of radius 12 cm has a charge of `1. 6 xx 10^(-7) C ` distributed uniformly on its surface. What is the electric field
at a point 18 cm from the centre of the sphere ?

Text Solution

Verified by Experts

Electric field at a distance 18 cm from the centre,
`E' = ( 1)/( 4pi in_(0)) ( q)/( r^(2)) = 9 xx 10^(9) xx ( 1.6 xx 10^(-7))/( ( 0.18)^(2))`
`= 4.44 xx 10^(4) N.C^(-1)`
