An electric dipole of dipole moment 4xx...

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.

Text Solution

AI Generated Solution

To determine the torque exerted by the electric field on the dipole, we can use the formula for torque (\(\tau\)) on an electric dipole in a uniform electric field: \[ \tau = \mathbf{p} \times \mathbf{E} = p \cdot E \cdot \sin(\theta) \] Where: - \(\tau\) is the torque, ...
