Question

An observer 'A' sees an asteroid with a radioactive element moving by at a speed = 0.3 c and measures the radioactivity decay time to be T A ′ ​ . Another observer ' B ' is moving with the asteroid and measures its decay time as T B ​ . Then T A ​ and T B ​ are related as below

Due to time dilation the interval between two events at the same point in a moving frame appears to be longer by a factor γ ( 1 − c 2 v 2 ​ ​ 1 ​ ) to an observer in a stationary frame. Time dilation is independent of the direction of velocity and depends only on its magnitude.
