Explain how you came to that conclusion. (2) X X X X 2. Measurements of a particle track shows a radius of deflection of 9.72 x 104m for a proton traveling at a speed of 5.92 X 10'm/s perpendicular to a 5.89 T magnetic field. Calculate the charge to mass ratio for the proton. (3) 3. Particle-antiparticle annihilation happens in stars. One of these reactions is a proton and an antiproton colliding to create two gamma rays. Write the equation for this reaction and determine the total amount of energy released by the gamma rays. . Put your answer in MeV. (3)
