Question

The mass of a particle is m. In order for its total energy to be twice its rest energy, its momentum must be:
A) mc/2 
C) mc 
E) 2mc

Quizplus · Accepted Answer

The total energy of a particle is given by E = sqrt((pc)^2 + (mc^2)^2), where p is the momentum, c is the speed of light, and m is the mass of the particle. If we want the total energy to be twice its rest energy (mc^2), we can set E = 2mc^2 and solve for p. This gives us p = sqrt(3)m*c. Therefore, the momentum of the particle must be 11eaafb7_ffe1_903d_a7a5_f925a9959329_TB3150_11.
