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.
For an atom to be charged, it must have a difference in the number of protons and electrons. Large objects also become charged when they have an imbalance in the number of protons and electrons. If there are more protons than electrons, the object will be positively charged, and if there are more electrons than protons, it will be negatively charged. Charge that is transferred between objects by rubbing them together is called static electricity.
