An electron is placed a distance of 1.1x10m from an unknown charge. The electron is released and moves away from the unknown charge (which is held stationary.) By observing the electron, you deduce that 5.3x10 18) of energy is lost once the electron has arrived at a distance of 3.8x10 4m from the unknown charge. What is the size and sign of the unknown charge? (Give your answer in x10 14C.)
