According to special theory of relativity the mass of a particle
-
- increases with increase in velocity with respect to an observer.
- decreases with increase in velocity.
- decreases with decrease in velocity.
- is independent of its velocity.
- increases with increase in velocity with respect to an observer.
Correct Option: A
According to the Special Theory of Relativity, the mass of a moving object measures more as its velocity increases until, at the speed of light, it becomes infinite. This is because as an object gains speed, it gains more (kinetic) energy.
