Question

In the arrangement shown in figure ma = m and mg = 2m, while
all the pulleys and string are massless & frictionless. At t = 0, a
force F = 10 t starts acting over central pulley in vertically
upward direction. Find
(a) Time at which both the masses lose contact with floor.
(b) Velocity of A when B loses contact with floor.
[Take all the units into S.I. system, take m = 1 kg and g = 10 m/s​
