An electric dipole with dipole moment 4 xx 10^(-9) Cm is aligned at 30° with the direction of a uniform electric field of magnitude 5 xx 10^4 NC^(-1). Calculate the magnitude of the torque acting on the dipole. |

Answer» Solution :TORQUE exerted on given DIPOLE, `vec(tau) = vecp xx vecE` `therefore tau = pEsin THETA` `=(4 xx 10^(-9)) (5 xx 10^(4))SIN 30^(@)` `tau = 10^(-4) Nm` (In the direction of `vecp xx vecE`) |
