A disk is rotating with some angular velocity as part of an isolated system. A particle on the rim of the disk has a mass of 5.0 µg. The instantaneous tangential velocity of the particle is (80.0 î + 80.0 ĵ) m/s. The position of the particle is (5.0 i - 2.0 j ) m. In order to increase the velocity of the particle, an external force of (2.0 î + 3.0 j ) N is applied. Select the correct instantaneous angular momentum of the particle before the external force is applied and the torque acting on the particle after the force is applied.
