’x.(a.) What is the mass (rest energy) of the particle after the collision in MeV? (b.) Show numerically that the gain in rest energy is equal to the photon’s energyminus the particle’s kinetic energy after the collision.
L⃗ relative to the origin when the particle is at r⃗ =(2.5j^+4.3k^)m. At position r⃗ a force of F⃗ =4.1Ni^ is applied to the particle. Find the torque relative to the origin.
