two small identical spherical conductor ( point charges ) , 0.6 meters apart from each other , have a combined charging at 200 uC . They repel each other with a force of 120 N.

( a) Calculate the charge on each conductor .
( B ) the two conductors are brought together so that an electrical contact occurs and is then apart so that it is
100 uC on each conductor . Calculate the force that one wire exerts on the other conductor
When they are 0.6m Apart.

hello @IrishBoy123 Yea so $$q=\sqrt{\frac{ F*r^2 }{ k }}$$

anonymous · Answer

could you draw up this for me? I have a hard time picturing it..

anonymous · Answer

okey, but a) is the equation i wrote before? but what is b)?

anonymous · Answer

the same thing but 100 uC?

irishboy123 · Answer

sorry.

the question is slightly misleading.  let me start again.  you know that $$q_1 + q_2 = 200 \mu C$$

also that
$$F = \frac{k q_1 q_2}{r^2}$$

so you can get a second equation for $$q_1 q_2 = [something] $$from Coumumbs law, and then solve.
