... Charges are arbitrarily called positive and negative. In most cases, only the negative charge is mobile. Properties of charge Like charges repel, unlike charges attract. Charge is conserved: it cannot be created or destroyed. Charges aren’t “used up”, but their energy can be “harnessed”. Electrons a ...

Physics 10-02 Magnetic Fields and Force on a Moving Charge
... possibility for such a futuristic energy source is to store antimatter charged particles in a vacuum chamber, circulating in a magnetic field, and then extract them as needed. Antimatter annihilates with normal matter, producing pure energy. What strength magnetic field is needed to hold antiprotons ...

... 5 x 10^14/s. With this frequency and the Planck constant, E is derived as: 7.2 x 10^ -11 ergs which is the energy in one shell of the incident light. The experimental value of the kinetic energy of the emitted photoelectron is 8 x 10^ -11 ergs. So close! This proves that the orbital electron is ejec ...
