Find the initial momentum of electron if the momentum of electron is changed by `p_(m)` and the De Brogile wavelength associated with it changed by `0.50%`

The angular momentum of p electron is

The angular momentum of p electron is

If the momentum of electron is changed by P_(m) then the de-Broglie wavelength associated with it changes by 0.50%. The initial momentum of electron will be:

If the momentum of an electron is changed by Delta p , then the de - Broglie wavelength associated with it changes by 0.50 % . The initial momentum of the electron will be

The kinetic energy of an electron gets tripled, then the de-Broglie wavelength associated with it changes by a factor

If the momentum of an electron is changed by p , then the de - Broglie wavelength associated with it changes by 0.5 % . The initial momentum of electron will be
