Calculating Electric Potential Energy Between Two Point Charges
A system consists of two point charges, \(q_1 = +2.0 \\mu C\) and \(q_2 = -3.0 \\mu C\), separated by a distance \(r = 5.0 \\text{ cm}\). Calculate the electric potential energy of this system. Use Coulomb’s constant \(k = 9.0 \\times 10^9 \\text{ N m}^2 \\text{C}^{-2}\). Provide your answer in joules (J).
Calculation and Nature of Electric Force Using Coulomb’s Law
Two point charges, \(q_1 = +2.0 \times 10^{-6}\text{ C}\) and \(q_2 = -3.0 \times 10^{-6}\text{ C}\), are fixed in a vacuum separated by a distance of \(0.40\text{ m}\). Use the Coulomb constant \(k = 9.0 \times 10^{9}\text{ N m}^2\text{ C}^{-2}\).
