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
