Click For Summary
An electric dipole with a magnitude of 0.2 Cm is placed in a uniform electric field of 100i + 70j + 40k N/C and is rotated from the x-axis to the y-axis. The work done by the external agent during this process is calculated as the negative change in potential energy, resulting in -6 J. The torque exerted by the electric field on the dipole must be calculated using the cross product of the dipole moment and the electric field. In the final orientation, the dipole is in static equilibrium, meaning the torque from the hand must equal the negative of the electric field's torque. Understanding the relationship between these torques is crucial for solving the problem accurately.
