Let us consider the case shown in the figure. A charged particle moving in a circular path on a plane, and a magnetic field B is directed into the plane. The magnetic force on the particle causes the particle to move clockwise along a circle of radius R. (a) Does the particle have a positive charge or a negative charge? (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 ? Explain Particle
