Two identical spheres each carry a charge of -40.0 µC. The spheres are separated by a distance of 2.00 m. What is the electric force between the spheres? (k_e = 8.99*10⁹ N·m²/C²)

Question

Quizplus · Accepted Answer

The electric force between two charges is calculated using Coulomb's law: F = k_e * |q1 * q2| / r^2. Substituting the given values: F = (8.99 x 10^9 N·m²/C²) * (40.0 x 10^-6 C)^2 / (2.00 m)^2 = 3.60 N. Since both charges are positive, the force is repulsive.
