1-Dimensional forces Three fixed particles exist in a straight line, The first particle is of charge 5.0 10-6 C. The second particle is of charge -5.0 10-6 C and located 20.0 cm to the right of the first charge. The Third particle is of charge -7.5-10-6 C and located 15.0 cm to the left of the first charge. (a) What force do they exert on a fourth particle of charge -2.5 10-6 C that is 13cm to the right of the first charge? (Include magnitude and direction) (b) What is the force of the fourth particle is instead it had a charge of 3.12-10-C and is still located at 13cm to the right of the first charge? (Include magnitude and direction) (a) (b)
