A positive point charge of 10^-4 C is located 3 m from another positive point charge of 10^-5 C.Their mutual electric potential energy is A)3 J B)2 J C)1 J D)zero E)-1 J

Question

Quizplus · Accepted Answer

The electric potential energy (U) between two point charges is given by the formula U = k * (q1 * q2) / r, where k is Coulomb's constant (approximately 8.99 x 10^9 N m²/C²), q1 and q2 are the charges, and r is the distance between them. Substituting the given values, U = (8.99 x 10^9) * (10^-4 * 10^-5) / 3 = 3 J.
