Two thin hollow plastic spheres, about the size of a ping-pong ball with masses (1=2=
0.002 kg) have been rubbed with wool. Sphere 1 has a charge 1=
-6 × 10-9 C and is at location < 0.43, -0.24, 0 > m. Sphere 2 has a charge 2=
-9 × 10-9 C and is at location < -0.5, 0.38, 0> m. It will be useful to draw a diagram of the situation, including the relevant vectors.
