n electric dipole of moment (\mu^{-}) of 400 µC m is placed in a transverse electric field (E^{-}) of 50 Vm ^{-1} at an angle of 30° to E^{-} . Then a torque of

Correct Answer is : 10−2 Nm acts along the direction of −E and −µ

10^{-2} Nm acts along the direction of E^{-}

10^{-3} Nm acts along the direction of \mu^{-}

10^{-5} Nm acts along the direction of E^{-} and \mu^{-}

10^{-3} Nm acts along the direction of E^{-}

10^{-2} Nm acts along the direction of E^{-} and \mu^{-}
