Questions
A man is raising himself and the crate on which he stands with an acceleration of 5 ms-2 by a massless rope-and-pulley arrangement. Mass of the man is 100 kg and
that of the crate is 50 kg. If g=10 ms-2, then the tension in the rope is
detailed solution
Correct option is B
m1=100kg,m2=50kg,a=5ms−2T+N−m1g=m1aT−N−m2g=m2aSolving these: T=1125 N and N=375 NSimilar Questions
