The ratio of the De-Broglie wavelength for the electron and proton moving the same velocity is `m_p-Mass ` of proton,`m_e-` Mass of electron)

Options

A. `m_p:m_e`
B. `m_p^2:m_e^2`
C. `m_e:m_p`
D. `m_e^2:m_p^2`

Answer

c

Explanation

The De-Broglie wavelength for moving electron and proton is given by,
`lambda_e/lambda_p=((h)/((m_ev)))/((h)/m_pv)=m_p/m_e=m_p:m_e`
