3. The figure below shows two tiny charged spheres q1 = +5 JC and q2 = -7.5 JC separated by 8.0 cm. a) Draw and label the electric fields at pointp and determine the magnitude and direction of the electric field at point P. b) If q3 = -3.2 mC is placed at point P, draw and label the FBD of q3 and determine the magnitude and direction of the force on q3. 4.0 cm P 4.0 cm 42
