Five equal-mass particles (A-E) enter a region of uniform magnetic field directed into the page. They follow the trajectories illustrated in (Eigure 1). Part C Rank the particles on the basis of their speed. Rank from largest to smallest. To rank items as equivalent, overlap them.

In an old-fashioned television, a beam of electrons is accelerated to a speed of 2.3 × 106 m /s and then directed to the flat screen, a distance d = 0.05 m from the end of the accelerator, using magnets, as shown in the figure below. The mass of an electron is 9.1 × 10-31 kg. a. An electron, having just left the accelerator and traveling in the x direction, enters a region of uniform magnetic field, B = 1.5 x 10-4 T in the y direction. What is the force on the electron due to the magnetic field? Be sure to specify both the magnitude and direction. b. What is the radius of curvature of the path of the electron as it moves from the accelerator to the screen? c. With what speed does the electron hit the screen? d. How far from the center of the screen does the electron hit? That is, how far is the electron deflected by the magnetic field? В y accelerator d

A particle of mass 7.7 x 10-8 kg and charge +10 µC is traveling due east. It enters perpendicularly a magnetic field whose magnitude is 4.3 T. After entering the field, the particle completes one-half of a circle and exits the field traveling due west. How much time does the particle spend in the magnetic field? Number i Units
