Question and diagram attached.
Electric Potential Energy A +3.0-nC charge Q is initially at rest a distance of 10 cm (r1) from a +5.0-nC charge q fixed at the origin. Naturally, the Coulomb force accelerates Q away from q, eventually reaching 15 cm (r2). What is the work done by the electric field between r1r1 and r2r2? How much kinetic energy does Q have at r2r2? My question is about the image attached. The part in the equation circled in blue is positive, and the part circled in red is negative. Can you explain how that negative sign appeared?
