A particle of +e charge is analyzed with a mass spectrometer that has a magnetic field B = 0.050 T. If the particle has a mass of m=2.0×10−27 kg and a speed of 8.0×105 m/s, what is the radius of the path? Express your answer with the appropriate units.

A charge with q = 2 C moves with a velocity of (4i + 10j + 4.4k) m/s and experiences a magnetic force of (8i – 12j + 20k) N. The x- component of the B field is zero. Determine the y and z components of the B field.

A 0.140-kg baseball, pitched at 47.5 m/s horizontally and perpendicular to the Earth’s horizontal 5.00 × 10-5 T field, has a 110-μC charge on it. What distance, in meters, is it deflected from its path by the magnetic force, after traveling 30.0 m horizontally? You may ignore the deflection due to gravity, which is going to be much larger than this.

A Hall probe serves to measure magnetic field strength. One such probe consists of a poor conductor 0.121 mm thick, whose charge‑carrier density is 1.27×1025⁢ m−3.
