1. You know that the magnetic field is nonzero in a certain region of space, but the magnitude anddirection of the field are unknown. You decided to shoot charged particles into the region to probethe unknown magnetic field. You observe that a proton moving at 1.5 km/s in the +x-directionexperiences a force of 2.25 x 10-16 N in the +y-direction, and an electron moving at 4.75 km/s inthe -z-direction experiences a force of 8.5 x 10-16 N in the +y-direction. The charge of a proton is1.6 x 10-1⁹ C, and the charge of an electron is -1.6 × 10-1⁹ C.(a) What is the magnetic field in the region?(b) What is the magnetic force on an electron moving in the -y-direction at 3.2 km/s?

You are assigned the job of building a very sensitive magnetic scale. Objects are hung from a horizontal rod through which an electric current is directed from left to right. The rod is loosely attached to a pair of vertical rails that allow it to slide up and down with almost no resistance. The entire scale is placed in an external magnetic field, and the current is adjusted until the rod and object levitate, balancing the downward gravitational force with an upward magnetic force. B? 1. In which direction must the external magnetic field point in order for your scale to work? 2. What current is needed to balance the scale if the combined mass of the rod and object is 1 kg, the length of the wire is 1 meter, and the magnitude of the external magnetic field is 0.1 Tesla?
