Question

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

Answer 1

`lamda=h/(sqrt(2mqV))`
` rArr" "lamdaprop1/sqrtV`
`"slope = "lamda/(1//sqrtV)prop1/sqrtq`
`rArr" "qprop1/("slope"^(2))" "({:("more the slope"),("less the charge"):})`
