An electron and a proton are detected in a cosmic ray experiment, the first with kinetic energy 10 keV and second with 100keV. Which is faster, the electron or proton ? Obtain the ratio of their speeds. Take mass of electron `9.11xx10^(-31)kg`. Mass of proton `=1.67xx10^(-27)kg` and `1eV=1.6xx10^(-19)J.`
