two point charges of 2 c and -3c are separated by 6cm what is the magnitude of the electrostatic force between them? and is the force attractive or repulsive? explain and what happens to the magnitude of the force when the distance is increased by a factor of 2 to 12cm
Hint: Use Coulomb's Law.
Increasing the separation by a factor of 6 will decrease the (attractive) force by a factor of 36.
