Question

a parallel plate capacitor of capacitance C has plates of area A with distance d between them. When the capacitor is connected to a battery of potential difference V, it as a charge of magnitude Q on its plates. While the capacitor is connected to the battery, the distance betwen the plates is decreased by a factor of 5. the magnitude of the charge on the plates and the capacitance are then :

a) 5 Q and 1/5 C.

b) 1/5 Q and 1/5 C.

c) 1/5 Q and 5 C.

d) 5 Q and 5 C.

Answer 1

d)
