Q1:

Assertion (A): Dielectric constant is independent of temperature unless the temperature is extremely high. Reason (R): For normal temperatures the number of atoms per unit volume is constant.

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

For normal temperatures the dielectric constant depends on the number of atoms per unit volume.
