Electrostatics Question 56

Question: When a slab of dielectric material is introduced between the parallel plates of a capacitor which remains connected to a battery, then charge on plates relative to earlier charge [MP PET 1992]

Options:

A) Is less

B) Is same

C) Is more

D) May be less or more depending on the nature of the material introduced

Show Answer

Answer:

Correct Answer: C

Solution:

When dielectric is introduced, the capacitance will increase and as the battery remains connected, so the voltage will remain constant. Hence according to $ Q=CV, $ the charge will increase.
