Question

A particle having zero mass its speed will be ​

Answer 1

Answer:

If a particle has no mass (m = 0) and is at rest (p = 0), then the total energy is zero (E = 0). ... In summary, all objects with no mass can never be at rest and must travel at speed c in all reference frames. Light is such an object, and the universal speed limit c is named the speed of light in its honor.

Answer 2

Explanation:

If a particle has no of mass ( m = 0 ) and is at rest

( p = 0) ,Then the mass of total energy is zero ( E = 0 ).
