At what speed, as a fraction of c, is a particle’s total energy twice its rest energy?

The speed of particle is 0.866c.

We have given that, particle’s total energy twice its rest energy.

We know that the formula of total energy is :

Here, m = mass of particle

v = velocity of particle

= Lorentz factor

We have given that total energy is twice of rest mass energy.

Here = total energy

= rest mass energy

Substituting in the formula of total energy :

We know that , substituting this value of :
