(a) If two protons are traveling parallel to each other in the same direction and at the same speed, is the magnetic force between them (i) attractive or (ii) repulsive? (b) Is the net force between them (i) attractive, (ii) repulsive, or (iii) zero? (Assume that the protons’ speed is much slower than the speed of light.)

As shown in the figure, an electron is fired with a speed of 3.43 x 106 m/s through a hole in one of the two parallel plates and into the region between the plates separated by a distance of 0.20 m. There is a magnetic field in the region between the plates and, as shown, it is directed into the plane of the page (perpendicular to the velocity of the electron). Determine the magnitude of the magnetic field so that the electron just misses colliding with the opposite plate. electron

An electron is accelerated through 2.70 103 V from rest and then enters a uniform 2.80-T magnetic field. (a) What is the maximum magnitude of the magnetic force this particle can experience? (b) What is the minimum magnitude of the magnetic force this particle can experience?

In a mass spectrometer, the mass of a particle is determined by it's circular path in a magnetic field of value B= 1T. Here, we consider a particle of charge q=te = 1.6 x 10"C that is accelerated across a potential difference AV :- 500 Volts. As shown, this particle enters a chamber with a uniform magnetic field. The particle makes a circular path and strikes the detector a distance I=8 Cm from where it entered the chamber. Part A Determine the mass of the particle. Vo AEO m 3= kg
