The electrostatic potential energy of two protons separated by 2.6 × 10^-15m is approximately

Question

Quizplus · Accepted Answer

The electrostatic potential energy of two point charges can be calculated using the formula U=kq1q2/r, where k is Coulomb's constant (9×109 Nm2/C2), q1 and q2 are the charges of the two objects (in this case, both are protons with charge +1.602×10-19 C) and r is the separation distance between them (2.6×10-15 m). Substituting these values into the formula, we get U=(9×109 Nm2/C2)(1.602×10-19 C)2/(2.6×10-15 m)=8.99×10-14 J. This is the electrostatic potential energy of the two protons, so the answer is E (8.9×10-14 J).
