The accompanied figure shows an arrangement for measuring mass of ions by an instrument called the mass spectrometer. An ion of mass m and charge +q is produced essentially at rest in source S, a chamber in which a gas discharge is taking place. The ion is accelerated by a potential difference and allowed to enter a region of constant magnetic field B q. In the uniform magnetic field region, the ion moves in a semicircular path striking a photographic plate at a distance x from the entry point. Derive a formula for mass m in terms of B0, q, Vacc, and x.

Explain how electromagnetic waves are a natural outcome of the principles of electromagnetism.
Neurons in our bodies carry weak currents that produce detectable magnetic fields. A technique called magnetoencephalography, or MEG, is used to study electrical activity in the brain using this concept This technique is capable of detecting magnetic fields as weak as 1.0 1015 T. Model the neuron as a long wire carrying a current and find the current it must carry to produce a field of this magnitude at a distance of 4.0 cm from the neuron.
Figure 5 shows a simple mass spectrometer, designed to analyze and separate atomic and molecular ions with different charge-to-mass ratios. In the design shown, ions are accelerated through a potential difference, V, after which they enter a region containing a uniform magnetic field. They describe semi-circular paths in the magnetic field and land on a detector a lateral distance x from where they entered the field region, as shown. Assume that there is no magnetic field in the accelerating region of the initial electric field, and no electric field in the semicircular path region. With the situation shown in Figure 5, are the ionspositively or negatively charged? Clearly explain yourreasoning.
An electron is sent through a mass spectrometersimilar to the diagram shown below. The electron startsfrom restandis accelerated East byan electric potential difference of 120 V. It then passes into a uniform magnetic field of magnitude 0.12T [North]. The electron follows a curve path, changing direction by 180° before it strikes a sensor.What is the displacement of the electron from the time it enters the magnetic field to the time it has changed direction by180°?(note: diagram below shows positive chargesentering the mass spectrometer)
Imagine an electron is moving from left to right with velocity, v, in a chamber. Inside the chamber, a magnetic field is working directed vertically upward (out of the page). Draw and show the trajectory of the electron and write down the reason of deflection. Don,t copy from anywhere. Must answer follow question. Do all step.
MASS SPECTROMETER: URANIUM SEPARATION II. In the figure below, what would happen to the separation distance d if the magnetic field is increased? (The uranium isotopes are singly ionized and are exposed to the same strength of magnetic field.) Increases. Decreases. Remains the same. Cannot be determined. I need more information.
A rail gun used electromagnetic forces to accelerate a projectile to very high velocities. The basic mechanism of acceleration is relatively simple and can be illustrated in the following example. A metal rod of mass m and electrical resistance R rests on parellel horizontal rails (that have negligible electric resistance) which are distance L apart as shown in figure 1. The rails are also connected to a voltage source delta V, so a current loop is formed. The vertical magnetic field, initially zero, is slowly increased. When the field strength reaches the value B0, the rod, which was intially at rest, begins to move. Assume that the rod has a slightly flattened bottom so that it slides instead of rolling. Use g for the magnitude of all the free fall acceleration. (A) find the coefficient of static friction between the rod and the rails.
Please answer with complete solution.A beam of electrons (of charge −e and mass me) is shot into a region of uniformmagnetic field with a speed of 35 m/s. They exit the region of uniform magnetic field opposite the direction they had entered. How strong must the magnetic field be such that each electron stayed in the region for a total of 70 ms? Answer should be in me/qe unit.
