Question

if a person is pushing a box By force F inside a moving train the work done in the frame of the earth will be ?

​

Answer 1

Answer:

Explanation:

zero

F→.(x¯+s¯0)

F→.S→

F→.S→0

Answer :

B

Solution :

Displacement w.r.t. ground =vess+s→0

Since train is moving with constant velocity net force acting on block is =F→

Therefore work done−F→.(S→+s→0)).
