Q1:

Assertion (A): If an electron having charge e is revolving in an orbit of radius R and with angular velocity ω, the magnetic dipole moment of orbit is 0.5 eωR2. Reason (R): Orbital angular momentum and magnetic dipole moment are always equal.

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:C - A is true but R is false

Orbital angular momentum and magnetic dipole moment are not equal.
