A point charge `+Q` is placed at a distance r from a short dipole of dipole moment `vecp` as shown in figure. The line joining the point charge Q to the centre dipole is perpendicular to dipole moment `vecp`, which of the following statement are true?

A

The net electrostatic force on the dipole is zero

B

The electrostatic force on the dipole is `(Qp)/(4 pi epsi_(0)r^(3))` and is acting along the dipole moment p

C

Torque acting on the dipole is `(Qp)/(4 pi epsi_(0) r^(2))` in the inward direction

D

Torque acting on the dipole is `(Qp)/(2 pi epsi_(0)r^(2))` in the outward direction
