Two point charges of 2 C and –3 C are separated by 6 cm.
1. Is the force attractive or repulsive? Describe.
2. What is the magnitude of the electrostatic force among them?
3. What happens to the magnitude of the force when the distance is increased with a factor of 2 to 12 cm?
4. What happens to the magnitude of the force when the distance is decreased with a factor of 3 to 2 cm?
