Negative charge –Q is distributed uniformly over the surface of a thin spherical insulating
shell with radius R.
Part A Calculate the magnitude of the force that the shell exerts on a positive point charge q
located a distance r>R from the center of the shell (outside the shell).
Express your answer in terms of the variables q, Q, r, R, and constants π and ϵ0.
Part B Find the direction of the force that the shell exerts on a positive point charge q located a
distance r>R from the center of the shell (outside the shell).
Part C Calculate the magnitude of the force that the shell exerts on a positive point charge q
located a distance r
Express your answer in terms of the variables q, Q, r, R, and constants π and ϵ0.
