Assertion (A): From the slope of the line in Figure, we can find permanent dipole moment of the molecules. Reason (R): Total polarization of a polyatomic gas is given by P = N(ae + ai + μ2p / 3kT)E.

Assertion (A): From the slope of the line in Figure, we can find permanent dipole moment of the molecules.

Reason (R): Total polarization of a polyatomic gas is given by P = N(ae + ai + μ2p / 3kT)E.

305-1

[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

Answer: Option A

Explanation:

The slope of the line in figure is 26-306-1

Since the total polarization is as given by the expression, we can find the permanent dipole moment of the molecules from the slope.
