`H^(+),He^(+)` and `O^(2+)` all having 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 `O^(2+)` are 1 amu, 4 amu, and 16 amu respectively. Then :

Options

A. `H^(+)` will be least deflected
B. `He^(+)andO^(+2)` will be deflected equally
C. `O^(+2)` will be deflected most
D. all will be deflected equally

Answer

B
