Force due to multiple charges, SHM problems involving charged particles

Force on Charge Particle

Electric potential due to multiple point charges and continuous charge distributions including spherical symmetries

Figure, shown above, shows three situations involving a charged particle and a uniformly charged spherical shell. The charges and radii of the shells are indicated in the figure. If F_(1),F_(2) and F_(3) are the magnitudes of the force on the particle due to the shell in situations (I),(II) and (III) then
