Question

56. Two particles carrying charges q- 4 HC and q2- 12HC are located 5 m apart. Choose a coordinate system where the first particle is at the origin, and the second is at x -5 m In this coordinate system, an electron sits at (2 m, -3 m) (a) Draw a diagram showing the vectors you need in order to determine the direction of the separate electric forces exerted on the electron by the particles. (b) Calculate the vector sum of these two forces. .. 58. Charged particles 1, 2, and 3 (qi - 5.0 uC, q24.00 HC, and q3 - -3.00 uC) are arranged at the vertices of a square of side 1 m, with particles 2 and 3 occupying opposite vertices Determine the position of particle 4, carrying the same charge as particle 1, such that the total electric force on particle 1 is zero.
