Time of flight (TOF) is routinely used to distinguish between different particle species.Calculate the difference in time interval required for a proton (rest mass 938 MeV/c²) and a muon (rest mass: 106 MeV/c²) to travel 2.5m,if each have a momentum of 255 MeV/c. A) 8 ns B) 15 ns C) 18 ns D) 10 ns

The time of flight for each particle can be calculated using the formula $ t = \frac{d}{v} $, where $ v $ is the velocity of the particle. The velocity can be found using the relativistic relation $ v = \frac{pc^2}{E} $, where $ E = \sqrt{(pc)^2 + (m_0c^2)^2} $. Calculating the velocities for both the proton and the muon and then finding the time difference for 2.5m gives approximately 8 ns.
