Calculate the force between a 0.006 C charge and a 0.001 C charge 4 meters apart.

Answers

The required force between the two charges is approximately 3371.25 N.

What is Coulomb's law?

The force between two point charges can be calculated using Coulomb's law, which states that:

F = k * (q₁ * q₂) / r²

where F is the force between the charges, k is the Coulomb constant, q₁ and q₂ are the magnitudes of the charges, and r is the distance between them.

In this case, we are given that one charge has a magnitude of 0.006 C and the other has a magnitude of 0.001 C, and they are separated by a distance of 4 meters. So we can substitute these values into Coulomb's law to find the force:

F = (8.99 x 10⁹ ) * [(0.006 ) * (0.001 )] / (4 )²

F = 3371.25 N

Therefore, the force between the two charges is approximately 3371.25 N.
