For the situation shown in figure (assume r >> length of dipole), mark out the correct statement(s).

Force acting on the dipole is zero.

Torque acting on the dipole is $\mathrm{pQ}/4{\mathrm{\pi \epsilon }}_0{\mathrm{r}}^2$ in clockwise direction. 

Force acting on the dipole is approximately $\mathrm{pQ}/4{\mathrm{\pi \epsilon }}_0{\mathrm{r}}^3$ and is acting upward.

Torque acting on the dipole is $\mathrm{pQ}/4{\mathrm{\pi \epsilon }}_0{\mathrm{r}}^2$ in anti-clockwise direction.
