An alpha particle and a proton are accel...

An `alpha` particle and a proton are accelerated from rest by a potential difference of 100V. After this, their de-Broglie wavelengths are `lambda_a`
and `lambda_p` respectively. The ratio `(lambda_p)/(lambda_a)`, to the nearest integer, is.

Text Solution

Verified by Experts

The correct Answer is:
`3`

`h/lambda=p=sqrt(2mqV)`
`implies lambda_(P)/lambda_(alpha)=sqrt((m_(alpha)q_(alpha))/(m_(P)q_(P)))=sqrt(4xx2)=sqrt(8)~~3`
