A metal sheet which is parallel to the plates of the capacitor and whose thickness is slightly less than the separation between these plates is now allowed to fall under gravity though the plates, without touching them.Which of the following correctly describes the motion of the metal plate as it passes through the plates of the capacitor? (a) It will move with a constant acceleration equal to g the acceleration due to gravity. (b) It will move with a constant acceleration less than g. (c) It will move with a constant acceleration greater than g. (d) It will move with variable acceleration less than the acceleration due to gravity.
