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.
A positively charged particle has great difficulty penetrating a target nucleus because the target nucleus has. 1. a positive charge, which repels the particle 3. the protection of surrounding electrons. 2. a negative charge, which attracts the particle 4. a very high binding energy. 6. In a fusion reaction, reacting nuclei must collide.
