lambda(e),lambda(p) and lambda(alpha) ar...

`lambda_(e),lambda_(p)` and `lambda_(alpha)` are the de-Broglie wavelength of electron, proton and `alpha` particle. If all the accelerated by same potential, then

A

`lamda_e lt lamda_p lt lamda_alpha`

B

`lamda_e lt lamda_p gt lamda_alpha`

C

`lamda_e gt lamda_p lt lamda_alpha`

D

`lamda_e gt lamda_p gt lamda_alpha`

Text Solution

Verified by Experts

The correct Answer is:
D
`lamda=h/(sqrt(2mqV))implies prop 1/(sqrt(mq))`
`lamda_egt lamda_pgt lamda_alpha`
