  • Question 4/10
    4 / -1
    A solid sphere of mass M, radius R and having moment of inertia about an axis passing through the centre of mass as I, is recast into a disc of thickness t, whose moment of inertia about an axis passing through its edge and perpendicular to its plane remains I. Then, radius of the disc will be

  • Question 6/10
    4 / -1
    A thin wire of length l having density ρ is bent into a circular loop with C as its centre, as shown in the figure. The moment of inertia of the loop about the line AB is

    Solutions

  • Question 7/10
    4 / -1
    A lamina is made by removing a small disc of diameter 2R from a bigger disc of uniform mass density and radius 2R, as shown in the figure. The moment of inertia of this lamina about axes passing through 0 and P is Io and Ip , respectively. Both these axes are perpendicular to the plane of the lamina.
