Q1:

A liquid has N permanent dipoles μp per unit volume and has been subjected to dc field for a long time such that orientation polarization is P0. At t = 0, the field is suddenly removed, then polarization

A will remain constant at P0

B will become zero at t = 0

C will delay to zero with a time constant

D either b or c

ANS:C - will delay to zero with a time constant
