Question

Two point charges \( +2 \, \mu\text{C} \) and \( -3 \, \mu\text{C} \) are placed 10 cm apart in vacuum. What is the electrostatic force between them?

• A. 4.5 N
• B. 9 N
• C. 18 N
• D. 2.25 N

Hint:

Remember: Coulomb's law is used to calculate the electrostatic force between two point charges: \( F = k \frac{|q_1 q_2|}{r^2} \).
