Two negative charges that are both - 5.0 * 10 ^ - 3 * C push each other apart with a force of 15 N. How far apart are the two charges ?

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

Argon, neon, and xenon are examples of

When the magnetic domains in a material can be aligned, but eventually drift out of alignment, the material is
