Problem
Two identical positive charges, each +5.0μC, are fixed 0.30 m apart. A third charge q3=−5.0μC is initially located exactly midway between them. Calculate the change in total electric potential energy if q3 is moved to a point 0.30 m directly above the midpoint, forming an isosceles triangle with the two fixed charges.
