2. Three charges lie along the x - axis as shown in Figure 1. 2m -q3 +q1 Figure 1. The positive charge q1 = + 15.0HC, is at x = 2m and positive charge q2 = + 6.0uC is at the origin. a. Sketch the direction of all the forces acting on ql, q2 and 93 individually b. Where must the negative charge q3 be placed on the x - axis such that the resultant force on it be zero? . Find the magnitude of the resultant force on qi due to q3. . Find the magnitude of the resultant force on q2 due to q3. . Sketch the triangle showing the physics of the problem in Q2 in x-y cartesian coordinates. [30marks]
