Consider the two objects below. One is very small (point object) with mass m, and
the other is a very thin circular arc of radius R whose mass is uniformly distributed.
The object of mass m is located at the center of the circle of the arc. The
linear density, mass per unit length, of the arc is λ. The full angle
that the arc subtends is α=(n1/n2)π.
Find the magnitude of the net force on the object of mass m.
If the magnitude of the net force on the object equals F=(Gmλ/R)
what is n3? Note that all the integers are unitless,
