Question

calculate the torque on each dipole of dipole moment P each, placed perpendicular to each at a distance of r​

Answer 1

The corresponding values of torque on dipoles are F+ = + q.E sin θ and F- = - q.E sin θ

Explanation:

As we know that the dipole moment is

p = q E

E is the electric field and q is the charge.

Now we know that

Torque = Force x distance

τ = q.E d sin θ

The value of torque on positive and negative charges.

F+ = + q E sinθ

F - = - q E sin θ
