Problem 1a: Velocity Selector: Show that with the right ratio of electric to magnetic field strength a particle of velocity v will proceed through both fields in a straight line at constant speed (hint: you will need an equation containing v. Also: what does the straight line at constant speed give you?). Assume that the angle of the velocity vector relative to the magnetic field vector is 90 degrees. (15 points) b: Show mathematically that the charge magnitude and sign...

List at least 5 properties and applications in which electric and magnetic fields differ: (i.e. A=> The direction of the electric field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge, and radially inwards toward a negative point charge. This makes electric fields more straight forward to integrate. Meanwhile, magnetic fields exert forces on moving charges and its direction is perpendicular to...

A proton travels through uniform magnetic and electric fields. The magnetic field is in the negative x direction and has a magnitude of 2.37 mT. At one instant the velocity of the proton is in the positive y direction and has a magnitude of 2550 m/s. At that instant, what is the magnitude of the net force acting on the proton if the electric field is (a) in the positive z direction and has a magnitude of 5.33 V/m, (b)...
