two identical brass balls mounted on wooden posts initially have different amounts of charge, one plus 3 uC and the other plus 15 uC. The balls are allowed to touch and then separate again. What is the final charge on each ball?
I've tried this problem again and again using conservation of momentum and energy but I am not having any luck: A ball of mass 0.300kg that is moving with a speed of 8.0m/s collides head-on and elastically with another ball initially at rest. Immediately after the collisio...
