An electric dipole of dipole moment `4xx10^(-5)` Cm is placed in a uniform electric field of `10^(-3) N//C` making an angle of `30^(@)` with the direction of the field. Determine the torque exerted by the electric field on the dipole.

Answer

`2xx10^(-8) Nm`

Explanation

Here, `tau = pE sin theta = 4xx10^(-5)xx10^(-3)xx sin 30^(@)`
`= 2xx10^(-8) Nm`
