1. b]1. The problem statement, all variables and given/known data Two large metal plates are held tightly together. Two equal and opposite point charges are placed one each on either side of the plates, and equidistant from them. The line joining the two charges is perpendicular to the plane pf the plates. What will happen when the two plates are released? 2. Relevant equations There would be an electric field at the location of each plate due to the external charges. 3. The attempt at a solution The electric field at the plates due to the external charges would be equal and opposite, and hence the net field at the plates would be zero. Moreover the induced charges on the plates would be equal and opposite. Hence there should be no force of attraction or repulsion acting on the plates when they are held together. However, I am unable to figure out as to how to proceed with analysis of the scenario when the two plates are separated from each other.
