... 1. Alpha particles have a positive charge. It was therefore concluded that electrostatic repulsion from a like charge, of very large mass, was required to produce a large angle deflection. However, as large angle deflections were very rare, and most alpha particles were undeviated from their origina ...

Charged Particles in Magnetic Fields
... Suppose a particle with charge q and mass m moves with velocity vector v. If a force F acts in the same direction as the velocity v then the particle continues to move in the same direction, but it speeds up. This is what an electric field can do to charged particles. We can describe it a bit differ ...

The principle effect of gravitational potential
... We have defined gravitational potential Φ as the work which must be done against the force of gravity per unit mass to slowly remove an object to an infinite distance. This is always expressed as a negative quantity. When a mass m falls from a height with a gravitational potential Φ to a height with ...
