Consider the figure below. (a) 0 + 5 10 x (cm) +9 -29 +9 (b) 0 5 10 -29 +9 +39 x (cm) -9 a. Find the total Coulomb force on a charge of 5.9 nC located at x = 1.5 cm in part (b) of the figure, given that q = 9.1 C. (Indicate the direction with the sign of your answer.) 2.1476 N b. Find the x-position (between x = figure. 7 cm 0 cm and x = 14 cm) at which the electric field is zero in part (b) of the
