A parallel-plate capacitor is clamped to a stand such that its plates are vertical. It remains connected to a cell through a centre-zero galvanometer. A metal sheet which is parallel to the plate of the capacitor and whose thickness is slightly less than the seperation between these plates is now allowed to fall under gravity though the plates, wihtout touching them.
Which of the following correctly described the motion of the metal plate as it passes through the plates of the capacitors ?
A. It will move with a constant acceleration equla 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 accelration greater than g.
D. It will move with variable acceleration less than the accelaration due to gravity.
