A solar-powered vehicle developed at Massachusetts Institute of Technology can reach an average speed of 60.0 km/h. Due to the presence of Earth’s magnetic field, a
magnetic force acts on the electrons that move through the car’s circuitry. Suppose an
electron moves at 60.0 km/h perpendicular to Earth’s magnetic field. If a 2.0 x 10x22
N force acts on the electron, what is the magnetic field strength at that location?

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.
