A proton traveling at 3.60 km/s suddenly enters a uniform magnetic field of 0.750. T, traveling at an angle of 55.0 degrees with the field lines (a) Find the magnitude and direction of the force this magnetic field exerts on the proton. (b) If you can vary the direction of the proton's velocity, find the magnitude of the maximum and minimum force you could achieve, and show how the velocity should be oriented to achieve these forces. (c) What would the answers to part (a) be if the proton were replaced by an electron traveling in the same way as the proton?
