Question

A student has three identical metal spheres, K, L, and M, on insulated stands equally spaced in a line as shown below. The charges on the spheres are Qk = +3C, QL = -5C, QM = +2C, P K L M 8A. The direction of the net force on sphere L due to spheres K and M is: a) to the left of the page b) to the right of the page c) toward the top of the page d) toward the bottom of the page 8B. At point P, the direction of the net electric field is mostly a) to the left of the page b) to the right of the page c) toward the top of the page d) toward the bottom of the page 8C. the spheres are touched together and separated, without grounding, in the following order: Step I Spheres K and L Step II Spheres K and M Step III Spheres L and M Which of the following rows indicates the final charge present on each sphere? Row Sphere K Sphere L Sphere M A. 0 0 0 B. -x -x +2x C. +x/2 -x +x/2 D. +x/2 -x/4 -x/4
