A man is sitting inside a moving train and observes the stationary objects outside of the train. Then choose the single correct choice from the following statements`-`

Options

A. all stationary objects outside the train will move with same velocity in opposite direction of the train with repsect to the man.
B. stationary objects near the train will move with greater velocity & objects far from train will move with lesser velocity with respect to the man.
C. large objects like moon or mountains will move with same velocity as that of the train.
D. all of these

Answer

A

Explanation

`vec(V)_(O,M)=vec(V)_(O)-vec(V)_(M)`
`vec(V)_(O,M)=vec(V)_(O)-vec(V)_("Train")`
`V_(O,M)` =velocity of object with respect to man
`V_(O)`= velocity of object
`V_(M)` =velocity of man
Here velocity of object is zero.
So, `vec(V)_(O,M)=-vec(V)_(M)`
