A deuteron and an alpha particle having ...

A deuteron and an alpha particle having equal kinetic energy enter perpendicular into a magnetic field. Let `r_(d) and r_(alpha)` be their respective radii of circular path. The value of `(r_(d))/(r_(alpha))` is equal to :

Text Solution

Verified by Experts

The correct Answer is:
2
For circular path in magnetic field.
`r = (mv)/(qB) = (sqrt(2mE_(x))/(qB))`
So,

`r_(1) : r_(2) = sqrt(2) : 1`
