Question

Three charges are attached to the vertices of a triangle as shown in the figure below. Assume that the positions of the -0.6 JC and the +0.8 PC charges formed the +y-axis and the -0.6 pc and the +1.0 PC charges formed the +x-axis. +0.80 uc 10.0 cm 8.0 cm -0.60 4C +1.04C (a) Determine the x-coordinate of the +0.8 C charge. m (b) Determine the y-coordinate of the +0.8 C charge. m (c) Determine the x-coordinate of the +1.0 C charge. m (d) Determine the y-coordinate of the +1.0 C charge. m (c) Calculate the x-component of the force that the +1.0 pc charge exerts on the +0.8 PC charge. N (Calculate the y-component of the force that the +1.0 C charge exerts on the +0.8 PC charge. N
