Q1. An iron plate 30 cm thick is magnetized to saturation in a direction parallel to the surfaces of the plate. A 20 Gev muon moving perpendicular to the surface enters the plate and passes through it with relatively little loss of energy. Estimate approximately the angular deflection of the muon's trajectory, given that the rest mass of muon is 100Mev and that the saturation magnetization in iron is equivalent to 1.6 x 10^23 electron moments per cm^3.
Q2. A proton high above the equator approaches the Earth moving straight downward with a speed of 365. Find out the acceleration of proton, given that the magnetic field at its altitude is 4.10×10-5.
