Question

Two babies are born in a moving train, one in the compartment adjacent to the engine and other in the compartment adjacent to the guard. According to the train frame, the babies are born at the same instant of time. Who is elder according to the ground frame?

Answer 1

Answer:

the first baby is elser

Answer 2

According to the ground frame, the baby adjacent to the guard cell is elder.

Explanation:

• It is to be noted here that the clocks’ moving frame is out of synchronisation and the train is in the moving frame.
• If v is the moving frame’s speed and the rest length is L0 untying the clocks, then the rear end clock leads the clock at the front by L0v/c2.
• So, the baby adjacent to the engine is younger to the baby adjacent to the guard.
