1.	A hollow sphere and solid sphere of the same radius rotate about their diameters with the same angular velocity and angular momentum. Then the ratio of their masses isA. `3:8`B. `5:8`C. `3:5`D. `5:3`
Answer» Correct Answer - C `(I_(1))/(I_(2))=((2)/(3)m_(1)R_(1)^(2))/((2)/(5)m_(2)R_(2)^(2))=(5m_(1))/(3m_(2)) " " therefore (m_(1))/(m_(2))=(3)/(5)`
