Question

To the passenger sitting in a train moving with a velocity V, the relative velocity of the train is

Answer 1

Answer:

Explanation:

VELOCITY OF TRAIN=V

VELOCITY OF TRAIN WRT PASSENGER=-V

RELATIVE VELOCITY=V-(-V)

=2V

Answer 2

The relative velocity of train w.r.t passenger is zero.

Given:

• Velocity of train = v
• Passenger is sitting inside train.

To find:

• Relative velocity of train w.r.t passenger?

Calculation:

First of all, let's see that proper velocity w.r.t proper reference frames :

• Velocity of train w.r.t ground = v

Since the passenger is also sitting in the train, we can say :

• Velocity of passenger w.r.t ground = v

Now, velocity of train w.r.t passenger :

$\boxed{v_{t p} = v_{tg} - v_{pg}}$

• Here 't' is train , 'p' is passenger and 'g' is ground.

$\implies v_{t p} = v - v$

$\implies v_{t p} = 0$

So, velocity of train w.r.t passenger is zero.
