An alpha particle (the nudeus of a helium atom) (with charge +2) is accelerated and moves in a vacuum tube with kinetic energy 10 MeV. It passes through a uniform magnetic field of 1.88T, and traces a circular path of radius 24.6cm. Obtain the mass of the alpha particle. [leV = `1.6 xx 10^-19 J`, charge of electron = `1.6 xx 10^-19C`]
