Question

Two charges of \( +2 \, \mu\text{C} \) and \( -2 \, \mu\text{C} \) are placed 1 meter apart. What is the force between them?

• A. \( 9 \times 10^9 \, \text{N} \)
• B. \( 18 \times 10^9 \, \text{N} \)
• C. \( 4 \times 10^9 \, \text{N} \)
• D. \( 0 \, \text{N} \)

Hint:

Use Coulomb's law to calculate the force between two charges. Be sure to use the correct units and magnitude for the charges.
