On decreasing the distance between the two charges of a dipole which is perpendicular to electric field and decreasing the angle between the dipole and electric field, the torque on the dipole
increases
decreases
remains same
cannot be predicted
Solution
Since $\tau=p E \sin \theta$ on decreasing the distance between the two charges, and on decreasing angle $\theta$ between the dipole and electric field, $\sin \theta$ decreases therefore torque decreases.
