The Z0 boson, discovered in 1985, is the mediator of the weak nuclear force, and it typically decays very quickly. Its average rest energy is 91.19 GeV, but its short lifetime shows up as an intrinsic width of 2.5 GeV. what is the lifetime of this particle?

The lifetime of the particle is  

Explanation:

From the question we are told that

    The average rest energy is

    The intrinsic width is  

The lifetime is mathematically represented as

Where h is the Planck's constant with a value of    

substituting values

the diagram which shows forces as either balanced = same speed or unbalanced = accelerarting
