In the arrangement shown pulley and thread are mass less. Mass of plate is 20 kg and that of boy is 30 kg.
Then :

A

If normal reacton on the boy is equal to weight of the boy then the force applied on the rope by the boy is (150 g/7) newton

B

If the boy applies no force on the string then the normal reaction on him is 30 g

C

If the system is in equilibrium then the boy is applying 125 newton force on the rope

D

None of the above
