MHT CET 2022 Physics question

A parallel plate capacitor is charged and then disconnected from the charging battery. If the plates are now moved further apart by pulling them by means of insulting handles, then

(A)the capacitance of the capacitor increases
(B)the voltage across the capacitor increasesCorrect
(C)the energy stored in the capacitor decreases
(D)the charge on the capacitor decreases

Answer: (B)

Solution

After disconnection the charge is constant (D is false). Moving the plates apart increases , so decreases (A is false). Voltage \dfrac$
