Q1:

Assertion (A):r can be determined experimentally by measuring the capacitance of a parallel plate capacitor with and without the dielectric.Reason (R): Capacitance of a parallel plate capacitor = .

A Both A and R are true and R is correct explanation of A

B Both A and R are true but R is not correct explanation of A

C A is true but R is false

D A is false but R is true

ANS:A - Both A and R are true and R is correct explanation of A

By taking the ratio of the capacitance of the parallel plate capacitor with the dielectric to the capacitance of the capacitor without the dielectric, we can easily find relative permittivity.
