Question

coulomb,s laws equation plzzzzzzzzzzzzzzzzzzzzzzzz

Answer 1

Answer:

F=k q1 q2/r2

F = electric force

k = Coulomb constant

q_1, q_2 = charges

r = distance of separation

Answer 2

${\huge {\overbrace {\underbrace {\red{answer}}}}}$

The magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them.The force is along the straight line joining them. If the two charges have the same sign, the electrostatic force between them is repulsive; if they have different signs, the force between them is attractive.

Being an inverse-square law, the law is analogous to Isaac Newton's inverse-square law of universal gravitation, but gravitational forces are always attractive, while electrostatic forces can be attractive or repulsive.Coulomb's law can be used to derive Gauss's law, and vice versa. In the case of a single stationary point charge, the two laws are equivalent, expressing the same physical law in different ways.The law has been tested extensively, and observations have upheld the law on a scale from 10−16 m to 108 m.
