Bringing a charge qq from very far away to a positon close to another fixed charge changes the potential energy of the two charges by ΔU=−2.0nJΔU=−2.0nJ If the potential difference for the first charge is ΔV=−2.0VΔV=−2.0V, what is its charge?
Homework Answers
ΔU = q(ΔV)
so, q = ΔU/(ΔV)
= (-2nJ)/(-2V)
= 1 nC - the charge
