Physics Question on Electric Field

Two charges each of 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 of 10 dyne/C making 30º angle with E→\overrightarrow E, the magnitude of torque acting on dipole is:

A

1.0×10−8Nm1.0 × 10^{-8} Nm

B

2.0×10−10Nm2.0 × 10^{-10} Nm

C

4.0×10−10Nm4.0 × 10^{-10} Nm

D

1.5×10−9Nm1.5 × 10^{-9} Nm
