Q1

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 ' \(\overrightarrow{ E }\) ' of 10 dyne/C making \(30^{\circ}\) angle with \(\overrightarrow{ E }\), the magnitude of torque acting on dipole is:

a

\(4.0 \times 10^{-10} Nm\)

b

\(2.0 \times 10^{-10} Nm\)

c

\(1.0 \times 10^{-8} Nm\)

d

\(1.5 \times 10^{-9} Nm\)
