**Elena**, Wednesday, December 5, 2012 at 4:45pmm₁v₁²/2 =qU => v₁ =sqrt(2qU/m₁)

m₂v₂²/2 =qU => v₂=sqrt(2qU/m₂)

v₁/v₂=sqrt(2qU/m₁)/sqrt(2qU/m₂)=sqrt(m₂/m₁)

in magnetic field:

ma=qvBsinα

a=v²/R, α=90°, sin90°=1

m v²/R=qvB

R=mv/qB

R₁/R₂=(m₁v₁/qB)/ (m₂v₂/qB)=

=m₁v₁/m₂v₂=(m₁/m₂)•sqrt(m₂/m₁)=

= sqrt(m₁/m₂)

R₂=R₁•sqrt(m₂/m₁)=…
