Electric charge the charge of an electron is negative, "−e", while that of a proton is positive, "+e". Charged particles whose charges have the same sign repel one another, and particles whose charges have different signs attract. Coulomb's law quantifies the electrostatic force between two particles by asserting that the force is proportional to the product of their charges, and inversely proportional to the square of the distance between them. The charge of an antiparticle equals that of the corresponding particle, but with opposite sign. The electric charge of a macroscopic object is the sum of the electric charges of the particles
Randall (given name) Randall (given name) Randall is a masculine given name in English and German . Its modern use as a given name originates from the transferred use of the English–language surname "Randall", which in turn is derived from "Randolph". There are several variant spellings of the English given name; these include Randal, Randel, Randell, and Randle. The pet form is "Randy".
