A train in standing on a platform, a man inside a compartment of a train drops a stone. At the same instant train starts to move with constant acceleration. The path of the particle as seen by the person who drops the stone is:

A

parabola

B

straight line for some time & parabola for the remaining time

C

straight line

D

variable path that cannot be defined

Text Solution

Verified by Experts

The correct Answer is:
C
Relative to the person in the train, acceleration of the stone is `g` downward, a (acceleration of train) backwards.
according to his:`x=(1)/(2)at^2`,`Y=(1)/(2)gt^2`
`implies(X)/(Y)=(a)/(g)impliesY=(g)/(a)x` straight line
