Materials and Components

Assertion (A): In many materials, dielectric polarization causes mechanical distortion. Reason (R): If dielectric polarization causes mechanical distortion then mechanical distortion must cause dielectric polarization.

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

When an electric field is applied across a dielectric material then the dielectric material becomes polarized. This phenomenon is called dielectric polarization, which results in mechanical distortion.
