23. Asolid sphere of mass M and radius R spinsabout an axis passing through its centre making600 rpm. Its kinetic energy of rotation is(a) T MR(c) 80TMR(b) TMR2(d) 80T MR2

Answer»

Option DThe total kinetic energy (KE) of an object is given by:

KE=1/2mv2+1/2Iω2KE=1/2mv2+1/2Iω2

whereIIis the moment of inertia of the object andits angular momentum.
