If an electron and a proton have the same `KE`, the ratio of the de Broglie wavelengths of proton and electron would approximately be

A proton and a deuteron have the same velocity, what is the ratio of their de Broglie wavelengths ?

If an electron and a proton have the same de - Broglie wavelength , then the kinetic energy of the electron is

The de-Broglie wavelength of a proton and an electron are equal. The it follows that

An electron and a proton are accelerated by same voltage difference. Find the ratio of the de broglie wavelength of electron and proton

An electron and a proton have same kinetic energy Ratio of their respective de-Broglie wavelength is about

An electron and a proton have same kinetic energy Ratio of their respective de-Broglie wavelength is about

An electron and a proton have the same de-Broglie wavelength . Then the kinetic energy of the electron is

A proton and alpha particle have the same K.E. Their de Broglie wavelengths are in the ratio

One electron & one proton have equal energies ten ratio of associated de-Broglie wavelength will be-
