Q1: Assertion (A): For elemental dielectrics, P = Na_eE_i where N is number of atoms/m³, P is polarization, a_e is electronic polarization and E_i is internal electric field. Reason (R): In elemental dielectrics there are no permanent dipoles or ions.

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
