Two charged particles move in the same direction with respect to the same magnetic field. Particle 1 travels 5 times faster than particle 2. However, each particle experiences a magnetic force of the same magnitude. Find the ratio |q1|/|q2| of the magnitudes of the charges.
A charge of -7.53 μC is traveling at a speed of 6.07 × 10^6 m/s in a region of space where there is a magnetic field. The angle between the velocity of the charge and the field is 52.7°. A force of magnitude 7.18 × 10^-3 N acts on the charge. What is the magnitude of the magnetic field?
A proton, traveling with a velocity of 5.4 × 10^6 m/s due east, experiences a maximum magnetic force of 8.0 × 10^-14 N. The direction of the force is straight down, toward the surface of the earth. What is the magnitude and direction of the magnetic field B, assumed perpendicular to the motion?
