An object with a charge of +28 µC is placed at the origin. Another object with a charge of +49 µC is placed a distance of +36 cm from the first object along the x axis. A third object with charge -17 µC is moved from the (x,y) location (0,10) to (12,10), where the positions are given in cm. When the third object is moved this distance, what is the change in the potential energy?
