A painter is applying force himself to raise him and the box with an acceleration of 5m/s2 by a massless rope and pulley arrangement as shown in figure. Mass of painter is 100kg and that of box is 50kg. If g = 10m/s2, then:
(A) tension in the rope is 1125N
(B) tension in the rope is 2250N
(C) force of contact between the painter and the floor is 375N
(D) none of these
