Problem: A 30 nC charged particle and a 50 nC charged particle are near each other. There are no other charges nearby. The electric force on the 30 nC particle is 5.70×102N. The 50 nC particle is then moved very far away.
Afterward, what is the magnitude of the electric field at its original position?
