Question

$1\mu C$ charge is uniformly distributed on a spherical shell given by equation $x^2+y^2+z^2=25$. What will be intensity of electric field at a point $(1,1,2)$?

Answer 1

Radius of the spherical will be $=5$

charge $=1\mu C$ on spherical shell

Uniformaly charged spherical shell

Sphere : $x^2+y^2+2^2=25=5^2$

Electric field inside at the point $(1,1,2)$
