Question

Calvin touches a negatively charged Rod to a neutral metal sphere located on the insulated stand. what will happen to the electrons when the negatively charged rod touched the metal sphere

Answer 1

When the negatively charged rod is touched to the neutral metal sphere, some of the excess electrons from the rod will transfer to the sphere. The electrons will flow from the rod to the sphere until both objects reach an equilibrium state. This means that the sphere will become negatively charged as it gains electrons from the rod.
