What is the force between two point charges of +3 µC and -2 µC separated by a distance of 0.5 m?

What is the force between two point charges of +3 µC and -2 µC separated by a distance of 0.5 m?

Step 1: Identify the values of the charges. Charge 1 (q1) is +3 µC, which is +3 x 10^-6 C. Charge 2 (q2) is -2 µC, which is -2 x 10^-6 C.
Step 2: Identify the distance between the charges. The distance (r) is 0.5 m.
Step 3: Use Coulomb's law formula: F = k * |q1 * q2| / r^2, where k is Coulomb's constant (8.99 x 10^9 N m²/C²).
Step 4: Calculate the product of the charges: |q1 * q2| = |(3 x 10^-6 C) * (-2 x 10^-6 C)| = 6 x 10^-12 C².
Step 5: Calculate r squared: r^2 = (0.5 m)² = 0.25 m².
Step 6: Substitute the values into the formula: F = (8.99 x 10^9 N m²/C²) * (6 x 10^-12 C²) / (0.25 m²).
Step 7: Perform the multiplication: (8.99 x 10^9) * (6 x 10^-12) = 53.94 x 10^-3 N.
Step 8: Divide by 0.25: 53.94 x 10^-3 N / 0.25 = 215.76 x 10^-3 N = 1.2 N.
Step 9: The final answer is the force between the two charges, which is 1.2 N.
