Calculate the ratio of velocities of a moving electron to that of a proton associated with the same de Broglie wavelength. `[m_(e)=9.11xx10^(-31)kg,m_(p)=1.67xx10^(-27)kg,h=6.626xx10^(-34)J*s`]

Text Solution

Verified by Experts

As given in the question, `lamda_(e)=lamda_(p)`
`therefore (h)/(m_(e)v_(e))=(h)/(m_(p)v_(p))`
`therefore (v_(e))/(v_(p))=(m_(p))/(m_(e))=(1.67xx10^(-27))/(9.11xx10^(-31))=1833`
