Negative charge −Q is distributed uniformly over the surface of a thin spherical insulating shell with radius R.
Diano4ka-milaya [45]

Answer:

-(1/4πϵ0)Qq/r^2

Step-by-step explanation:

Firstly we have to assume the uniform shell of radius R as point charge as the point charge.

Then apply coulomb equation of electrostatic charge (Fe=q1q2/4πϵ0r2) where the q1 and q2 are point charges and r is the distance from the centre of charges.

But remember there's a condition that r>>R otherwise the charge will get non-uniformely distributed.
