A charged particle moves in the x–y plane, and a magnetic field B is directed into the plane as shown in Figure P20.38. The magnetic force on the particle causes the particle to move clockwise along a circle of radius R.
(a) Is the particle positively charged or negatively charged?
(b) The charge of the particle is increased by a factor of three, and the particle is found to move in a circle of radius R . What is the ratio R/R?
(c) The mass of the particle is decreased by a factor of four, and the particle is found to move in a circle of radius R. What is the ratio R’’/R ?'
