An ultra-relativistic electron radiates in a magnetic field of strength 2 × 10-6 T. The electron has an initial energy Eo. If after 276.1
years its energy is 50 MeV, determine Eo. Enter your answer in MeV to 1 decimal place.
The factor γ appears in many relativistic expressions. A value γ = 1.01 implies that relativity changes the Newtonian values by approximately 1% and that relativistic effects can no longer be ignored. At what kinetic energy, in MeV, is γ = 1.01 for (a) an electron, and (b) a proton?

Particles are initially held at rest, until one day they are released and fall under the influence of gravity. The fall of the particle certainly causes the particle to have a number of speeds, and this of course causes the particle to experience Lorentz forces at the same time as the gravitational force that affects the particle. Due to the influence of the Lorentz force, the particle will experience a bend so that there is a condition where the particle no longer has the velocity component ŷ and begins to move upward, say this state occurs at the lowest point of the particle's path. a) Determine the velocity of the particle at its lowest point. b) Same as part a), only if initially the particle is thrown downward with initial velocity u Kindly answer these questions.
