Question 10 (4 points) Three charged spheres sit along a horizontal axis. Sphere A has a charge of 3.5 JC. Sphere B is 25 cm to the right of A and has a charge of 2.6 uC. Sphere C is 40 cm to the right of Sphere A and has a charge of 1.0 uC. Calculate the net force experienced by sphere C. Consider a positive force as a force being directed to the right.
