B Magnetic field force

    I would like to fine the kinetic energy of a cone that rotates around its simmetry axis.
    I consider that the cone is formes by infinite cylinders with different radius and infinitesimal height. I end up with this result:
    K=1/4w^2R^2hM
    where w is the angular velocity R the radius h the height and M the mass of the cone.
    Could you please tell me wheter or not this is correct ?

    You can check your value of I for a cone here: https://en.wikipedia.org/wiki/List_of_moments_of_inertia

    The OP deleted their original question out of Post #1 after I replied (which is not allowed per the PF rules). The original post is restored, and the thread will remain closed.
