Questions
Two bodies have their moments of inertia I and 2 I respectively about their axis of rotation' If their kinetic energies of rotation are equal, their angular momenta will be in the ratio
detailed solution
Correct option is D
The kinetic energy of rotation K and angular momentum L are related asK=L22I or L2=2KI∴ L12L72=2K1I12K2I2=KIK×(2I)=12or ,L1L2=12or ,L1:L2=1:2Talk to our academic expert!
