1.	An electron and a proton are detected in a cosmic ray experiment , the first with kinetic energy 10 keV and the second with 100 keV.Which is faster , the electron or the proton ? Obtain the ratio of their speeds . (electron mass = 9.11 xx10^(-31) kg , proton mass = 1.67 xx10^(-27)kg , 1 eV = 1.60 xx10^(-19)J)
Answer» SOLUTION :`1.7 xx10^(9) HZ`
