Two metal plates each of area A form a parallel plate capacitor. Now one plate is displaced. Up, then the capacitance of capacitor decreases.
Due to displacing on plate, the overlapping area decreases, capacitance `C =(epsilon_(0)A)/(d)` decreases.

Options

A. Both A and R false
B. Both A and R true and R is not correct reason for A
C. A is true and R is false
D. Both A and R are true and R is correct reason of A.

Answer

D
