A beam of α particles (helium nuclei) is used totreat a tumor located 10 cnn inside...
2. A cyclotron is a device used to accelerate charged particles to high speeds. It consists of two hollow containers -called dees because of their shape facing each other and separated by a small gap. They are immersed in a uniform magnetic field, B, and are attached to a source of alternating voltage. A charged particle is projected from the center of the cyclotron into Dee #1, and the magnetic force causes it to turn in a cirele. When it...
A beam of alpha particles is fired horizontally with a speed of 1.5 x 10° m/s into a region where there is a vertical magnetic field of magnitude 0.388 T. An alpha particle is the nucleus of a helium atom and as such, consists of two protons, two neutrons, and has a mass of 6.64 x 10-27 kg. (a) Determine the length of time it will take an alpha particle to move halfway around a complete circle. 1.68e-7 s (b)...
As shown in the figure, an electron is fired with a speed of 3.73 x 10 m/s through a hole in one of the two parallel plates and into the region between the plates separated by a distance of 0.24 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...
A proton enters a region of constant magnetic field, perpendicular to the fie and after being accelerated from rest by an electric field through an electric potential difference of - 350 V. Determine the magnitude of the magnetic field, if the proton travels in a circular path with a radius of 21 cm. mt As shown in the figure below, when a charged particle enters a region of magnetic field traveling in a direction perpendicular to the field, it will...
1. A force of 5.78x10-16 N acts on an unknown particle that travels at a 90 ° angle through a magnetic field. the velocity of the particle is 5.65x104 m / s and the field is 3.20x10–2 T, how many elementary charges does the particle carry? 2.What potential must be applied to a source of mass ions (9.99x1027 kg) to be accelerated by a region where there is a 1.2 T perpendicular magnetic field, if the minimum electric field to...
