Two thin hollow plastic spheres, about the size of a ping-pong ball with masses (m1 = m2 = 2e-3 kg) have been rubbed with wool. Sphere 1 has a charge q1 = -6e-9 C and is at location < 40e-2, -20e-2, 0 > m. Sphere 2 has a charge q2 = -6e-9 C and is at location < -50e-2, 50e-2, 0> m. It will be useful to draw a diagram of the situation, including the relevant vectors.
.
What is the magnitude of the gravitational force exerted on q2 by q1?
