Question

A parallel plate capacitor of capacitance 90 pF is connected to a battery of EMF 20 V . If a dielectric material of dielectric constant K = 5 3 is inserted between the plates, the magnitude of the induced charge will be:, 0 . 9 nC, 1 . 2 nC, 0 . 3 nC, 2 . 4 nC

MARKS App · Accepted Answer

Induced charge on the dielectric, Q i n d u c e d = K C V 1 - 1 k = 5 3 × 90 × 10 - 12 × 20 1 - 3 5 = 1.2 nC .
