Re: Electrostatics problem



P.S. Of course, my geometric proof can be easily extended to the unequal
mass case treated by Michael. Simply replace step 3 with the following:

3. From the triangle of forces for body 1, the law of sines says:

sinT1/F = sinT3/(m1*g)

From the triangle of forces for body 2, the law of sines says:

sinT2/F = sinT3/(m2*g)

Thus, sinT1/sinT2 = m2/m1
