Coulomb's law in vector form F = r3kq1. . q2. . r. where, F is the coulombic (electrostatic) force acting between the two charges q1. .

The calculator below is about Coulomb's law. It allows you to calculate the unknown value (whether force, charge, or distance) using known values and scalar formula This calculator can be useful in solving school physics problems. Suppose a distance of 1.00 meter separates two point charges, each with a charge of +1.00 Coulomb.

The force exerted by one charge q on another charge Q is given by Coulomb's law: r is the distance between the charges. Remember that force is a vector, so when more than one charge exerts a force on another charge, the net force on that charge is the vector sum of the individual forces.

The electrostatic force between point charges and separated by a distance r is given by Coulomb’s law. Note that Newton’s third law (every force exerted creates an equal and opposite force) applies as usual—the force on is equal in magnitude and opposite in direction to the force it exerts on . (a) Like charges; (b) unlike charges.
