Unformatted text preview: Electrons and protons with the same kinetic energy are moving at right angles to a uniform magnetic field. How do their orbital radii compare? Lecture 14 Chapter 26 Page 6 Text Problem 26 – 45 A particle carrying a 50C charge moves with velocity k i v ˆ 2 . 3 ˆ . 5 + = m/s through a uniform magnetic field j i B ˆ 7 . 6 ˆ 4 . 9 + = T. a. Find the magnetic force m F on the particle. b. Form the dot products v F ⋅ and B F ⋅ to show explicitly that the force is perpendicular to both v and B . Text Problem 26 – 45 continued b. Form the dot products v F ⋅ and B F ⋅ to show explicitly that the force is perpendicular to both v and B ....
