An electric dipole is placed in a uniform electric field. The dipole will experience

An electric dipole is placed in a uniform electric field. The dipole will experience
  1. a force that will displace it in the direction of the field
  2. a force that will displace it in a direction opposite to the field.
  3. a torque which will rotate it without displacement
  4. a torque which will rotate it and a force that will displace it

Solution

When a dipole is placed in a uniform electric field, two equal and opposite forces act on it. Therefore, a torque acts which rotates the dipole.
