142428 According to de-Broglie hypothesis if an electron of mass ' $m$ ' is accelerated by potential difference ' $V$ ', then associated wavelength is ' $\lambda$ '. When a proton of mass ' $M$ ' is accelerated through potential difference of ' $9 \mathrm{~V}$ ', then the wavelength associated with it, is

1 $\lambda \sqrt{\frac{M}{m}}$
2 $\lambda \sqrt{\frac{\mathrm{m}}{\mathrm{M}}}$
3 $\frac{\lambda}{3} \sqrt{\frac{\mathrm{M}}{\mathrm{m}}}$
4 $\frac{\lambda}{3} \sqrt{\frac{m}{M}}$
