Three identical particles, A, B and C, each with charge q=10.00 micro Coulombs, are placed along a circle of radius r-1.00 m at angles 0, 90 and 180 degrees from positive x axis respectively. All angles are measured counterclockwise from positive x axis.
sketch qualitatively the net electric field at the center of the circle and the net coulomb force on the charge at 90 degrees.
Calculate the net electric field (both magnitude and direction) at the center of the circle. What is the net force (both magnitude and direction) experienced by the charge at 90 degrees.
Calculate net work done by the field due to the charges at 0 and 90 degrees to move the charge at 180 degrees to the center of the circle.
