Question
Plot a graph showing the variation of de Broglie wavelength (X) associated with a charged a particle of mass m, versus `1/sqrtV` where V is the potential difference through which the particle is accelerated. How does this graph give us information regarding the magnitude of the charge of the particle?

Solution
The slope of the graph is `h/sqrt(2mq)`considering we know the slope and mass of the charged particle we can easily calculate the charge.
