SUMMARY
The magnitude of the force between a +12 µC charge and a +2.7 mC charge, located 43 cm apart, can be calculated using Coulomb's law. The correct formula is F = k * q1 * q2 / r^2, where k is the Coulomb's constant (9 x 10^9 N m²/C²). After converting units to Coulombs and meters, the force is determined to be approximately 1.58 N. This calculation emphasizes the importance of using consistent units in physics equations.
