Question

1. A very small dipole of dipole moment p is
fixed on a line in xy plane. Centre of mass
of dipole lies on x-axis. A point charge Q is
fixed at origin. 0<o<90


x-axis
O
1) Electric force on dipole is parallel to
2) Electric force on dipole is parallel to ‘x' axis
3) About origin ‘O'net torque on dipole is in
clock wise sense

Answer 2

Answer:

• 4) Electrostatic interaction energy of dipole and point charge is negative​ is the correct option

A pair of equal and opposite electric charges whose centres do not coincide is known as an electric dipole. An induced electric dipole is an atom in which the centre of the negative cloud of electrons has been displaced slightly away from the nucleus by an external electric field. The atom loses its dipolarity when the external field is removed.
