Question

Li and a proton are accelerated by the same potential, their de Broglie wavelengths $\lambda_{Li}$ and $\lambda_p$ have the ratio (assume $m_{Li}$ = 9$m_p$ )
(a) 1 : 2
(b) 1 : 4
(c) 1 : 1
(d) 1 : $3\sqrt{3}$

Answer 1

Δli is proportional to 1/√mq i.e. 1√9*3e and for proton Δli is proportional to 1/√1*e do the ratio of  ΔLi to  Δp is 1/3√3
