A sphere of mass 10 kg and radius 0.5 m rotates about a tangent. The moment of inertia of the sphere is
5 kg m2
2.7 kg m2
3.5 kg m2
4.5 kg m2
C.
3.5 kg m2
M.I. about tangent = I + MR2
= MR2 + MR2
= MR2
= × (10) × (0.5 )2
M.I. about tangent = 3.5 kg m2
Angular momentum of the particle rotating with a central force is constant due to
Four point masses, each of value m, are placed at the corners of a square ABCD of side A. The moment of inertia through A and parallel to BD is
A wire elongates by
A ‘T’ shaped object with dimensions shown in the figure, is lying on a smooth floor. A force F is applied at the point P parallel to AB, such that the object has only the translational motion without rotation. Find the location of P with respect to C
