Which of the following observer is/are non inertial ?
- A child revolving in the merry go round
- A driver in a train moving with constant velocity v
- A passenger in a bus which is slowing down to a stop
Answer & explanation
Correct answer: option 3
Since centripetal acceleration is present in merry round it is non inertial frame of reference
Since bus is slowing down to a stop, it means it is experiencing a retardation, so it is non inertial frame of reference
Hence choice (a) and (c) are correct
