Question

Hello people ~
When a comb rubbed with dry hair attracts pieces of paper. This is because the______

(a) comb polarizes the piece of paper

(b)comb induces a net dipole moment opposite to the direction of field

(c)electric field due to the comb is uniform

(d) comb induces a net dipole moment perpendicular to the direction of field​

Answer 1

$\bold{Heya!}$

Answer :-

(b) comb induces a net dipole moment opposite to the direction of field.

Explanation :-

When a comb rubbed with dry hair it's attracts pieces of piece of paper. This is because the comb that induces of the dipole net that of the moment thatopposite of the field. And, This happens the field dueing to charge of the comb induces of the dipole moment in the paper of the molecules in the dielectric.
