A rope thrown over a pulley has ladder (of mass M - m) with a man of m

1.	A rope thrown over a pulley has ladder (of mass M - m) with a man of mass m on one of its ends and a counterbalancing mass M on its other end The man climbs with a velocity v_(r ) relative to a ladder. Pulley and rope are ideal. The velocity of centre of mass of the system is
Answer» `(m)/(M)v_(R )` `(m)/(2M)v_(r )` `(M)/(m) v_(r )` `(2M)/(m)v_(r)` ANSWER :B
