Magnetic field due to currentHard
Question
H+, He+ and O2+ all have the same kinetic energy pass through a region in which there is a uniform magnetic field perpendicular to their velocity. The masses of H+, He+ and O2+ are 1 amu, 4 amu and 16 amu respectively. Then
Options
A.H+ will be deflected most
B.O2+ will be deflected most
C.He+ and O2+ will be deflected equally
D.all will be deflected equally
Solution
i.e., r ∝
If K and B are same.
i.e., rH+ : rHe+ : rO2+
1 : 2 : 2 Therefore, He+ and O2+ will be deflected equally but H+ having at least radius will be deflected most.
