Question

Moment of inertia M . I . of four bodies, having same mass and radius, are reported as; I 1 = M . I . of thin circular ring about its diameter, I 2 = M . I . of circular disc about an axis perpendicular to disc and going through the centre, I 3 = M . I . of solid cylinder about its axis and I 4 = M . I . of solid sphere about its diameter. Then:

Quantrex Academy · Accepted Answer

Correct answer: C. I 1 = I 2 = I 3 &#62; I 4

Ring I 1 = M R 2 2 about diameter Disc I 2 = M R 2 2 Solid cylinder I 3 = M R 2 2 Solid sphere I 4 = 2 5 M R 2 I 1 = I 2 = I 3 &#62; I 4
