If a constant magnetic field is directed along the z-axis with a magnitude of 1.50 x 10- T, find the magnitude of the magnetic force acting on the ion and the magnitude of the ion's acceleration. HINT (a) the magnitude (in N) of the magnetic force acting on the ion 5.04e-21 2 X (b) the magnitude (in m/s2) of the ion's acceleration 7.766e4 x m/s2 Need Help? Read It Watch It 4 Submit Answer 5.
