A nitrogen ion (N+) moves in the xy-plane with a speed of 2.80 ✕ 103 m/s. If a constant magnetic field is directed along the z-axis with a magnitude of 2.75 ✕ 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

A positively charged particle of mass 6.82 x 10-8 kg is traveling due east with a speed of 64.2 m/s and enters a 0.397-T uniform magnetic field. The particle moves through one-quarter of a circle in a time of 4.06 × 10-³ s, at which time it leaves the field heading due south. All during the motion the particle moves perpendicular to the magnetic field. (a) What is the magnitude of the magnetic force acting on the particle? (b) Determine the magnitude of its charge. (a) Number (b) Number pi i Units Units V < B (out of screen)

One component of a magnetic field has a magnitude of 0.0383 T and points along the +x axis, while the other component has a magnitude of 0.0735 T and points along the -y axis. A particle carrying a charge of +2.22 × 10-5 C is moving along the +z axis at a speed of 4.97 x 10³ m/s. (a) Find the magnitude of the net magnetic force that acts on the particle. (b) Determine the angle that the net force makes with respect to the +x axis. (a) Number (b) Number i IN Units Units By +q
