Question

A solid sphere and a ring (of the same mass and the radius) are
rotating freely about their own tangential axis keeping the same
angular momenta If Ks and KR be the kinetic
energies of the solid sphere and the ring respectively, then :
(a) KS = KR (b) KS >
KR (c) KS < KR (d)
KS = 2 KR

A solid sphere and a ring (of the same mass and the radius) are rotating freely about their own tangential axis keeping the same angular momenta. If Ks and KR be the kinetic energies of the solid sphere and the ring respectively, then : (a) KS = KR (b) KS > KR (c) KS < KR (d) KS = 2 KR

A solid sphere and a ring (of the same mass and the radius) are rotating freely about their own tangential axis keeping the same angular momenta. If K_s and K_R be the kinetic energies of the solid sphere and the ring respectively, then :
(a) K_S = K_R (b) K_S> K_R (c) K_S < K_R (d) K_S = 2 K_R
