An electric dipole with dipole moment 4 ...

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

Text Solution

Verified by Experts

We are given: `p= 4 xx 10^(-9) C m, theta = 30° and E = 5 xx 10^(4) N C^(-1)`
Using relation, `pi = pEsintheta= 4 xx 10^(-9) xx 5 xx 10^(4) xx 1/2 = 10^(-4) N m`.
