If a particle moves with a speed of 1.5 ...

If a particle moves with a speed of `1.5 xx 10^(8)` m/s then the ratio of its mass to its rest mass is

A

1.155

B

11.55

C

15.15

D

1.515

Text Solution

Verified by Experts

The correct Answer is:
A
`m/m_(0)=1/sqrt(1-v^(2)/c^(2))=1/sqrt(1-((1.5xx10^(8))/(3xx10^(8)))^(2))`
`=1.155`
