Question

In a Hall-effect experiment, a current of 2.3 A sent lengthwise through a conductor 1.2 cm wide, 3.9 cm long, and 10 μm thick produces
a transverse (across the width) Hall potential difference of 8.4 µV when a magnetic field of 1.3 T is passed perpendicularly through the
thickness of the conductor. From these data, find (a) the drift speed of the charge carriers and (b) the number density of charge
carriers.

In a nuclear experiment a photon with kinetic energy 6.0 MeV moves in a circular path in a uniform magnetic field. If the magnetic field is B= 1.7 T what is the radius of the orbit?
The Hall affect is used to measure the carrier density of a thin sheet of electrons. When a current of 80.0 µA flows through the length of the electron sheet, which is 1.2-mm long, 0.27- mm wide and 12-nm thick, a magnetic field perpendicular to the sheet produces a potential difference of 0.53 mV across the width of the sheet. If the carrier density in the electron sheet is 6.74 x 1025 m-3, what is the magnitude of the magnetic field?

Solar cells generate a potential difference when exposed to sunlight. In an experiment, you wish to charge a rechargeable battery by connecting it in series to an array of solar cells. You perform the experiment outdoors, in direct sunlight, when the intensity of solar radiation is 1000 W/m². However, your solar cells only have an efficiency of 11% (that is, only 11% of the sunlight power transmitted to the solar cells is delivered to the rechargeable battery). While the circuit is connected, you measure at one instant the potential difference across the battery to be 5.30 V and the current in the circuit to be 0.27 A. What is the area of the array of solar cells? m2
