1.

the de Broglie wavelength associated with an electron is the same as that of a Proton given that a Proton is 1836 times as massive as an electron find the ratio of their Momenta and their kinetic energy​

Answer»

ANSWER:

since,the wavelenghts are equal so velocity of PROTON is equal to the electron's velocity.

LET,velocity of proton=velocity of electron=v

Also,let mass of electron be m.

Then mass of proton=1836m(Given)

So,ratio of their Momentum(Proton to electron)=1836m*v

––––––– = 1836:1

MV

And ratio of their K.E=(0.5*1836m*v²)/(0.5*m*v²)=1836:1
