a proton and electron have same debroglie wave length which of them moves fast? and which posses more kinetic energy explain? |
debroglie wavelength is h/mv where h is planck's constant.If they have the same debroglie wavelength they have the same momentum. m1v1=m2v2. Mass of proton is greater than that of electron and so velocity of electron is greater.Kinetic energy is 1/2 mv^2.So kinetic energy of electron is greater. |
