Homework Statement
Hi so i am having a problem understanding charge. The problem isTwo identical metal spheres on insulating stands are placed some distance apart. On one sphere is some amount of excess negative charge. On the other sphere is twice as much excess positive charge. Hanging midway between the two spheres on an insulating thread is a metal ball (a pendulum in effect). The ball of the pendulum is pushed gently to the side (with an insulating rod) until it contacts the positively charged sphere and then it is released.
This is not a calculation problem but more of a conceptual problem.
Homework Equations
no equations
The Attempt at a Solution
I am thinking that the metal ball would first start out postively charged as its already touching the positve sphere and then as it swings over the postive charge would attract the negative charge and then lose the positve charge as it swings back over and finally lose its negative charge once it swings back over again, and the process would continue until someone stopped the medal ball. But I am not sure. There could also be other questions related to this but not so sure what those could be as well.please help
