A proton, mass 1.67e-27kg and charge +1.6e-19C, moves in a circular orbit perpendicular to a uniform magnetic field of 0.86T. Find the time for the proton to make one complete circular orbit?

A proton travels at a speed 1.1 × 107 m/s perpendicular to a magnetic field. The field provokes the proton to move in a circular path of radius 0.975 m. What is the field strength, in tesla?

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 travel in a circular path. If the magnitude of the magnetic field is 0.180 T, the speed of the particle is 12.0 × 106 m/s, the radius of the trajectory of the path is 105.0 cm, and the charge has a magnitude of 3.20 × 10-19 C, determine the following. (a) sign of the charged particle positive O negative (b) mass of the particle (use the conversion 1 u = 1.66 x 10-27 kg) What kind of force must the particle experience in order to travel in a circle? What force provides the centripetal force needed to make the particle travel in a circle? What is the angle between the direction of the velocity of the particle and the direction of the magnetic field experienced by the particle? u

A proton moves with a speed of 963953 m/s. It is travelling in the xy plane. A magnetic field of 7.3 mT is pointing in the z-direction. What is the radius (in meters) of the circular path this electron will follow?

A singularly-charged ion (i.e. a neutral atom which has gained one electron) with kinetic energy of 7x10−15 J follows a circular path of radius 0.6m when placed in a magnetic field of 0.5T.   (Note that the charge of an electron is e = 1.6 x 10−19 C.)   a) Using the fact that the ion is going in a circular motion in a magnetic field, what is the ion’s momentum (in kg.m/s)? b) What is the ion’s speed (in m/s)? c) What is the ion’s mass (in kg)? d) An electric field is added to the experiment and adjusted so that the ion passes through without any deflection. What is the magnitude of this electric field (in T)?

A charged particle moves into a region of uniform magnetic field, goes through half a circle, and then exits that region. The particle is either a proton or an electron (you must decide which). It spends 130 ns in the region. What is the magnitude of B? Give your answer in T. (mproton=1.672x1027 kg, melectron-9.1lx10-3! kg, e-1.602x10-19 C) OB

An ion carrying a single positive elementary charge (+e) has a mass of 2.84E-23 g. It is accelerated through an electric potential difference of 1.01 kV and then enters a uniform magnetic field of B = 0.08 T along a direction perpendicular to the field. What is the radius of the circular path of the ion in the magnetic field? (Units: cm)

An electron moves in a circular path with a speed of 1.36 x 107 m/s in the presence of a uniform magnetic field with a magnitude of 1.84 mT. The electron's path is perpendicular to the field. (a) What is the radius (in cm) of the circular path? cm (b) How long (in s) does it take the electron to complete one revolution? S Read It

An electron with a speed of 2.5 x 106 m/s moves with a circle in a plane perpendicular to a uniform magnetic field. If the radius of the circle is 2.3 cm, then what is the magnitude of the field?
