Question

Expression for columb law

Answer 1

Explanation:

Coulomb's law states that: 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.

$f = k \times \frac{q1q2}{r2}$

Answer 2

Answer:

Coulomb's law formula

F is the force on q1 and q2 measured in newtons (N). k is Coulomb's constant k = 8.988×109 N⋅m2/C2. q1 is the first charge in coulombs (C). q2 is the second charge in coulombs (C). r is the distance between the 2 charges in meters (m).
