Charged Particle in a Magnetic Field Suppose that a particle of mass moves in a circular orbit of radius with a constant speed . As is well-known, the acceleration of the particle is of magnitude , and is always directed towards the centre of the orbit.
-Because the charged rod doesn't touch the sphere, no charge is added to or removed from the sphere. Instead, the rod attracts some of the sphere's negative charge to the side of the sphere near the rod. This leaves a deficit of negative charge on the opposite side of the sphere, so that side is now positively charged. The negative charge on the sphere is close to the rod so it is strongly attracted to the rod. The positively charge on the sphere is far from the rod, so it is weakly repelled by the rod.
