1.) A −50 nC charged particle is in a uniform electric field E→=(10 V/m,east). An external force moves the particle 1.0 m north, then 5.0 m east, then 2.0 m south, and finally 3.0 m west. The particle begins and ends its motion with zero velocity. How much work is done on it by the external force? What is the potential difference between the particle’s final and initial positions?

A particle that has an 8.9-µC charge moves with a velocity of magnitude 3.0 105 m/s along the +x axis. It experiences no magnetic force, although there is a magnetic field present. The maximum possible magnetic force that the charge with the given speed could experience has a magnitude of 0.43 N. Find the magnitude and direction of the magnetic field. Note that there are two possible answers for the direction of the field.
