An electron traveling horizontally with velocity 1.55 x10^{5} m/s enters a region where a uniform magnetic field is directed into the plane of the paper as shown. The electron has a mass of 9.11 x10^{-31} kg and a charge of -1.60 x10^{-19} C. The particle then enters a uniform 1.60-T magnetic field. If the particle's velocity is perpendicular to the magnetic feild at all times.
a). Describe and sketch the motion of the electron once it has entered the field on the paper. Identify the direction of the force acting over the electron.
b). What is the magnitude of the magnetic force exerted on the particle?

A ball has fallen to the street below, and a passerby returns it by launching it at an angle of 53.0° above the horizontal at a point 26.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above the wall.
Two test charges are located in the x-y plane. If q1 = -3.20 nC and is located at x = 0.00 m, y = 1.160 m and the second test charge has magnitude of q2 = 5.00 nC and is located at x = 1.00 m, y = 0.500 m, calculate the x and y components, Ex and ..
A crate is pulled by a force (parallel to the incline) up a rough incline. The crate has an initial speed of 1.5m/s. The crate is pulled a distance of 7.5 m on the incline by a 150 N force. The acceleration of gravity is 9.8m/s² mu=0.15
