Question

Assertion : If a dielectric is placed in external field then field inside dielectric  will be less than applied field.

Reason : Electric field will induce dipole moment opposite to field direction.

(a) Both A and R are true and R is the 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 and R are false

Answer 1

Correct option  (c) A is true but R is false

Explanation:

Dipole moment will be in the same direction as the external field. the collective effect of dipole moments produces a field that opposes the external field and hence. the net electric field inside the dielectric is less than the external electric field.
