Suppose I can induce a charge Q in a conducting sphere by the traditional induction method, then why is it that the charges would be equally shared if I put this sphere in contact with another identical sphere? (resulting in a charge Q/2 in either sphere)
My understanding is that the extra electrons in the first sphere would neutralize the positive charges in the second sphere, leaving a net negative charge in the second sphere. But why do the net negative charges on either sphere at the end of it have to be equal? (Q/2)
What is the theoretical maximum for the charge that can be transferred to another identical sphere?
Thanks in advance!
