    Solutions

  • Question 2/10
    4 / -1
    From a disc of radius R, a concentric circular portion of radius r is cut out so as to leave an annular disc of mass M. The moment of inertia of this annular disc about the axis perpendicular to its plane and passing through its centre of gravity is

  • Question 8/10
    4 / -1
    Two solid spheres (A and B) are made of metals of different densities ρA and ρB respectively. If their masses are equal, the ratio of their moments of inertia (IB / IB ) about their respective diameters is

    Solutions

  • Question 9/10
    4 / -1
    A solid sphere of radius R has moment of inertia I about its geometrical axis. If it is melted into a disc of radius r and thickness t. If its moment of inertia about the tangential axis (which is perpendicular to plane of the disc), is also equal to I, then the value of r is equal to
