A person sitting in the rear end of the compartment throws a ball towards the front end. The ball follows a parabolic path. The train is moving with uniform velocity of `20ms^(-1)`. A person standing outside on the ground also observers the ball. How will the maximum heights `(h_(m))` attained and the ranges (R) seen by thrower and the outside observer compare each other?

A

Same `y_(m)` differentR

B

Same `y_(m)`

C

Differentl `y_(m)` same R

D

Different `y_(m)` and R
