SUMMARY
The electric potential energy (U) of a system consisting of three equal point charges, each with a charge of 1.35 µC, positioned at the vertices of an equilateral triangle with sides measuring 0.350 m, is calculated using the formula U = k(Qq/r). The total potential energy is determined by finding the potential energy for each pair of charges and summing these values. The calculated total potential energy for this configuration is 0.138 J, confirming the approach of considering each pair due to equal distances and charges.
