A sample of radioactive material has an alpha emitter and a beta emitter . The energy of decay reactions are and respectively. The radiation coming out from the sample is passed through two parallel slits and to get a narrow parallel beam of alpha and beta particles. This beam is allowed to enter perpendicularly into a region of uniform magnetic field. The particles after taking a semicircular path strike the screen at point above the line and, below the line particles are found to strike the screen everywhere from to . The distance and and and respectively. Find the ratio . Take and assume that mass of alpha particle is 4 time the mass of a proton which is times the mass of an electron.
