A rope of negligible mass passes over a pulley of negligible mass attached to the ceiling, as shown in figure. One end of the rope is held by Student A of mass `70 kg`, who is at rest on the floor. The opposite end of the rope is held by Student `B` of mass `60 kg`, who is suspended at rest above the floor. The minimum acceleration `a_(0)` with which the Student `B` should climb up the rope to lift the Student A upward off the floor. `(g=10m//s^(2))`
