+12.0 μC 91 -24.0 uC 92 +36.0 μC 13 160 mm 160 mm Figure 3.2 b. Three (3) “point charges”, qı = +12.0 uC, q2 = -24.0 uC and q3 = +36.0 uC are positioned on the x-axis (the horizontal axis) as depicted in Figure 3.2. Note that charge q1 is positioned 160 mm to the left side of charge q2 while charge 43 is positioned 160 mm to the right side of charge (2. (Coulomb's constant, k = 9.00 x 109 Nm²/C2). Based on this information and Figure 3.2, find the direction and magnitude of the NET electrostatic force exerted on the point charge 42. (3 x 1 mark) =
