WebCharge to Mass Ratio for an Electron. Purpose Find the charge to mass ratio for an electron. Electric force on a charged particle: FE=qE (Eq. 1) q – charge, in C E – electric field strength, in V/m. Magnetic force on a charged particle: FB=qvB (Eq. 2) q – charge, in C v – speed, in. m s B – magnetic field strength, in T WebThe angle of deflection of a particle through an electric field is proportionate to its charge to mass ratio. The higher the charge, the stronger the attraction between the particle and electric field, hence greater deflection. The bigger its mass, more energy is required to change the direction of motion of the particle, hence smaller deflection.
