If a proton and electron have the same de Broglie wavelength, then

If proton and electron have same de-Broglie wavelength then….

Can a proton and an electron have the same de Broglie wavelength?

A moving proton and electron have the same de-Broglie wavelength. If K and P denote the K.E. and momentum respectively. Then choose the correct option :

A proton and an electron have same de Broglie wavelength. Which one has higher kinetic energy?

A proton and an electron have same de Broglie wavelength. Which of them moves faster and which possesses more kinetic energy ?

A proton and an electron have same de Broglie wavelength. Which of them moves faster and which possesses more kinetic energy ? Justify your answer.

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