Two large parallel metal plates, each having area A`, are oriented horizontally and separated by a distance `3d`. A grounded conducting wire joins them, and initially each plate carries no chatege. Now a thirdidentical plate carrying charge `Q` is inserted between the two plates, parallel to them and lacated a distance (d) from the upper plate, as shown in. What induced charge appears on each of the two original plates?
.

How will the voltage (V) between the two plates of a parallel plate capacitor depend on the distance (d) between the plates, if the charge on the capacitor remains the same?

A and B are two large identical thin metal plates placed parallel to each other at a small separation. Plate A is given a charge Q. (i) Find the amount of charge on each of the two faces of A and B. (ii) Another identical plate C having charge 3Q is inserted between plate A and B such that distance of C from B is twice its distance from A. Plate A and B is shorted using a conducting wire. Find charge on all six faces of plates A, B and C. (iii) In the situation described in (ii) the plate A is grounded. Now write the charge on all six faces.
