What is the Coulomb's law?

Answer 1

William Audy

#F=k(Q_1,Q_2)/r^2#

Suppose that there are two charges, Q_1 and Q_2.

Through this relationship, the force between them can be discovered.

#F=k(Q_1*Q_2)/r^2#

Where k is Coulomb's constant and #r# is the distance between the two charges

and the force is attraction if the two charges have different sign (#+ve and -ve#) and repulsion if the two charges have the same sign

Nora Arzate

Coulomb's law states that the electrostatic force between two charged particles is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them. It can be mathematically expressed as F = k * (q1 * q2) / r^2, where F is the force, q1 and q2 are the magnitudes of the charges, r is the distance between the charges, and k is Coulomb's constant.

Answer from HIX Tutor

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
