Structure of Atom · De broglie wavelength of accelerated particles

Two positively charged particles

m_1

and

m_2

have been accelerated across the same potential difference of 200 keV as shown below.

[Given mass of $m_1 = 1$ amu and $m_2 = 4$ amu]

The deBroglie wavelength of $m_1$ will be x times of $m_2$ . The value of x is . (nearest integer)
