Two charges of each magnitude 0.01 C and separated by a distance of 0.4 mm constitute an electric dipole. If the dipole is placed in an uniform electric field ' E ' of 10 dyne/C making 30 o angle with E , the magnitude of torque acting on dipole is:

1. 4.0 × 10 –10 Nm
2. 1.0 × 10 –8 Nm
3. 1.5 × 10 –9 Nm
