For the situation shown in figure. (assume r> >length of dipole) mark the correct statements

 

Force acting on the dipole is approximately $\frac{pQ}{4\pi {ϵ}_0{r}^3}$ and acting upward 

Force acting on the dipole is zero 

Torque acting on dipole is $\frac{pQ}{4\pi {ϵ}_o{r}^2}$ in CW direction

Torque acting on dipole is $\frac{pQ}{4\pi {ϵ}_0{r}^2}$ in ACW direction
