Two identical tiny metal balls have charges q1 and q2. The repulsive force one exerts on the other when they are 20 cm apart is 1.35x10^(—4) N. After the balls are touched together and then separated once again to 20 cm, the repulsive force is found to be 1.406 x 10^(-4) N. Find q1 and q2.

Solution:
Two identical tiny metal balls have charges q1 and q2. The repulsive force one e
