When charges moving in piece of material areeEHplaced into a region of magnetic field, they feel aforce according to F = q(v, × B). The deflection%3DevB+ + +/+ + + + + + +of these moving charges causes a difference inelectric potential to be produced in the materialperpendicular to both the direction of current,and the direction of the magnetic field. Thisdifference in potential is called the Hall voltage.Show that the Hall voltage across wires made of the same material, carrying identical currents,and subjected to the same magnetic field is inversely proportional to their diameters. (Hint:Consider how drift velocity depends on wire diameter).

A singly charged ion (an ion missing one electron) with a velocity of 7,642 m/s is injected perpendicular to a 0.277 T magnetic field, and the ion moves in a circle of 66.8 mm radius. What is the molar mass of the ion in grams? (Remember to use grams and Avogadro's number to get molar mass. State the answer as an integer with no unit.) Moving to another question will save this response. Question & of a
Write down an expression for the force experienced by an electron moving with a velocity, v, in a magnetic field B. By equating this expression to the force required to cause electrons to follow a circular path of radius, r, derive an expression for the ratio, (?⁄?) for an electron in terms of the magnetic field strength, the radius of the circular path and the accelerating potential, V.
Starting from rest, an electron is accelerated through a region between two oppositely charged plates, as shown in Figure 1. The distance between the plates is 10 cm and the magnitude of the potential difference between them is 100 V.
