Question

when would the wavelength associated with an electron be equal to the wavelength associated with four Proton mass of electron is 9.1 0 9 5 into 10 to the power minus 27 mass of proton is 1.67 25 into 10 to the power minus 24 gram​

Answer 1

Explanation:

we we know that wavelength = h/ MV

( where h is constant)

as per we know that, wavelength is associated with the electron is equal to the wavelength associated with the protons.

than,

h/ 4MV = h /mv

here m= mass of electron

v = velocity of electron

and,. M= mass of proton

V= velocity of proton

hence ,. 1/4MV = 1/mv

than, v= 4MV / m

hence, v= 4× 1.6725×10^-27 ×V / 9.1095×10^-31

hence , = 4×1837 V ( answer)
