Problem 4) An electron travels in a straight line with a relativistic speed v past a stationary proton. Assume that the electron passes by so quickly that its motion is unaffected by the presence of the proton, and that the proton is so heavy that it moves only negligibly as the electron passes by. If the distance of closest approach is b, calculate the momentum imparted to the proton in terms of v, b, and fundamental constants. Hint: Use eq....

An electron travels with velocity < 5 × 105, 0, 0 > m/s. It enters a region in which there is a uniform magnetic field of < 0, 0.6, 0 > T. What is the magnetic force on the electron? F(b)= < , , , > N Despite the magnetic force, the electron continues to travel in a straight line at constant speed. You conclude that there must be another force acting on the electron. Since you know there is...

• An electron, at rest, is accelerated through region 1, which has a 5000 V potential difference. It then enters region 2 where there is only a uniform magnetic field and it undergoes uniform circular motion (in a plane) of radius 0.954 mm. After subtending half a circle, the electron exits region 2, traveling in the opposite direction it was before entering region 2. (a) Draw a physical representation of this situation, complete with the direction of the electric and...
