    1. The problem statement, all variables and given/known data

    A rigid body is free to rotate about a fixed axis k through the origin. A force F
    is applied to the body at a point R. State the relationship between the torque due to
    F and the angular momentum about the axis. How is this related to Newton’s Second
    Law applied to linear momentum?

    2. Relevant equations



    3. The attempt at a solution

    So i know that Torque = rate of change of angular momentum..

    But Angular momentum = m(r x v) so how do i write an expression for it in this case?

    Also how does it relate to NII for linear momentum?

    THanks
