Two charges, q1 and q2, are at rest near a positive test charge, q, of
7.2.x 10^-6C. The first charge, q1 is a positive charge of 3.6 x 10'^-6C, located
0.025 m away from q at 35 degrees; q2, is a negative charge of -6.6 x 10^-6C
located 0.068 m away at 125 degrees.
a. Determine the magnitude of each of the forces acting on q.
b. Sketch a force diagram.
c. Graphically determine the resultant force acting on q.
