In order to raise a mass m a man ties it to a rope and passes the rope over a frictionless pulley. He climbs the rope with an acceleration 3g/2 relative to the rope. If the mass of the man is m/2 and the mass of the rope is negligible, the tension in the rope is
detailed solution
Correct option is C
given amR= am-aR= 3g2; am =3g2- aR as man and rope moving in oppsote direction equation for the man T-mg2=m2 am=m23g2- aR ; T=5mg4-12maR----1 equation for the mass T-mg=maR----2 solving for T we get T=7mg6Talk to our academic expert!
