The force on a point charge, q, located along the z axis due to a uniformly charged ring of total charge Q and radius R is given by KQqz/(z^2+R^2)^3/2.
A) Find the points along the z axis where the force is maximum.
B) What is the magnitude of this force.
C) Qualitatively draw the force as a function of z.
