In a certain vacuum tube, electrons evaporate from a hot cathode at a slow, steady rate and accelerate fromrest through a potential difference of 45.0 V. Then they travel 28.0 cm as they pass through an array of slitsand fall on a screen to produce an interference pattern. If the beam current is below a certain value, onlyone electron at a time will be in flight in the tube. In this situation, the interference pattern still appears,showing that each individual electron can interfere with itself. What is the maximum value for the beamcurrent that will result in only one electron at a time in flight in the tube?

Current is defined as the flow of charge per unit of time. It is measured in ampere or amp.…

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?
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. (a) Number M. i (b) Number i Units Units
Mammography is an x-ray imaging procedure for breast cancer diagnosis and screening. Assume that 20ke V x-ray is used in mammography. Also assume that the breast of a patient is 6 cm in thickness (soft tissue), and the propagation speed of x-ray photons in soft tissue is about the same as in vacuum. How long will it take for x- ray photons to travel through the breast?
Electrons enter a magnetic field traveling at v, = vỹ. The constant, uniform magnetic field B = 0.75 2 T acts as a filter curving the electrons to a small gap that only allows specific electron energies. The source of electrons enters the filter as a beam that is 15 micrometers in diameter and have a range of energies from 5-25 meV. The filter redirects the beam, as pictured, to the right v = và but does not speed them up. If the filter is to further narrow the range of energies from 5-25 meV to 10-12 meV, find the dimensions of the gap. In the picture, calculate ymin and ymer, both of which can be assumed to be equal to the radius of the paths taken within the magnetic field. %3D The beam being focused to 15 um at the start can be assumed to be a point source and take circular paths within the magnetic field.

In Millikan's experiment, an oil drop of radius 1.64 mm and density 0.851 gcm-³ is suspended in the capacitive chamber when a downward electric field of 1.92 x 105 NC-1 is applied. Find the charge on the drop, in terms of electron charge.
The main equation we are using to measure the e/m ratio is: (e/m)=((2v)/(r2B2)) If the anode voltage V is increased by 4 times and the magnetic field was kept constant, the electron beam's deflection radius will be doubled. If we plot V as the y-axis and r2 as the x-axis the slope is equal to: A) (e/m)B2=slope B)(e/m)=slope C)(e/m) (B2/2)=slope
