A bar magnet has magnetic dipole moment $$\overrightarrow M $$. Its initial position is parallel to the direction of uniform magnetic field $$\overrightarrow B $$. In this position, the magnitudes of torque and force acting on it respectively are -

Two charges 14 $$\mu$$C and $$-$$4 $$\mu$$C are placed at ($$-$$12 cm, 0, 0) and (12 cm, 0, 0) in an external electric field $$E = \left( {{B \over {{r^2}}}} \right)$$, where B = 1.2 $$\times$$ 10⁶ N/(cm²) and r is in metres. The electrostatic potential energy of the configuration is
