Two identical small spherical conductors (point charges), separated by 0.6 m, carry a total charge of 200 mu or micro CC. They repel one another with a force of 120 N. (For the universal constant k use the value 8.99 times 109 N m2/C2.)
so I used q1 + q2= 200e-6C
and q1*q2= Fr^2/k I solved for q1*q2 and plugged q1=200e-6 - q2 into that equation. used the quadratic formula and got q2 to be 200uC but this logically does not make sense because then q1 would have to be 0uC.
