NEET Questions Solved


Two masses M and m are attached to a vertical axis by weightless threads of combined length l. They are set in rotational motion in a horizontal plane about this axis with constant angular velocity ω. If the tensions in the threads are the same during motion, the distance of M from the axis is 

(1) MlM+m

(2) mlM+m

(3) M+mMl

(4) M+mml
