A potassium ion (K+) moves in the xy-plane with a speed of 3.00 x 10³ m/s. If a constant magnetic field is directed along the z-axis with a magnitude of 2.75 x 10- 5 T, find the magnitude of the magnetic force acting on the ion and the magnitude of the ion's acceleration. (a) the magnitude (in N) of the magnetic force acting on the ion (b) the magnitude (in m/s2) of the ion's acceleration m/s²
