A particle with negative electric charge is surrounded by four other coplanar particles with different charges as is shown in Figure 1. The charge is attracted to the positive charges, while repulsed by the negative charges. Note that the forces and geometry in this figure are not scaled. Figure 1 a) Using the parallelogram method, find the magnitude of the resultant of F1 and F2 forces and the angle it makes with the

axis in the clockwise direction. b) Given that the centre particle (at the origin of

system) is in equilibrium, what should be the magnitude of force

and the angle

. You can use any method.
