A massive ring radius a and mass m lies on the xy plane

A massive ring (radius = a and mass = M) lies on the xy plane. Calculate the force F on a test mass m at position z on the z axis.

Now assume a = 1 and GMm/a2 = 1 in some system of units.

A) What is the force on m at z = 0?

B) What is the force on m at z = a?

C) What is the maximum force on m?
