A particle with charge q = 33.4 mC and mass m = 7.18 mg has a kinetic energy of K = 4.84 mJ and is moving counter-clockwise on your screen on a circle of radius R = 80.0 cm. a. b. C. d. What is the speed of this particle? What is the magnetic field that it is sitting in? A field out of the screen will be positive and a field into the screen will be negative. What is the cyclotron angular frequency w of this proton? If we were to double the kinetic energy K and double the magnetic field B, what would be the new radius of the path?
