A particle with charge of 4 microcoloumbs is at the origin, another identical particle is placed 2 m from the origin on thepositive x-axis and another 2 m on the positive y-axis. Provide asketch with vectors representing the forces on the charge at theorigin due to the other two particles. Also include a third vectorrepresenting the sum of the 2 force (net force). Then calculate themagnitude and the direction of the net force on the particle at theorigin. Please show clearly how to solve for the magnitude and then direction.
