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

Force acting on the dipole is zero

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

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

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