A certain dipole has opposite charges of 2xx10^(-5) separated by a distance of 0.2mm. It is placed in a uniform electric field of 10^(3)Vm^(-1). (i) find the torque, the field exerts on the dipole when the dipole is at 60^(@) with respect to the field. (ii) find the work, it would take to rotate the dipole to this position starting with the dipole aligned parallel to the field |
