Question

12. A point charge q is located a distance a from the surface of a
sphere of radius 2a. A charge Q is distributed uniformly
throughout the volume of the sphere. The magnitude of the
electrostatic force between the point charge q and the sphere
is F, where
F =w = kawan​

Answer 1

i dont know this is your answer.

Answer 2

Answer:

F = $\frac{|qQ|}{4\pi\epsilon_{0} a^{2}}$

Explanation:

Spheres can be treated as point charges
