Show all your work for the following questions. Make sure to show all the formulas used and have proper significant digits to receive full marks. 1. If three spheres are in line like the picture below, with sphere A having a charge of 5.9C, Sphere B having a charge of -3.8 C and sphere C having a charge of -6.9C. Sphere A and B are 20 cm apart and sphere B and C are 25 cm apart. Determine the electrostatic force acting on sphere C. (Note the angle between ABC is 90 degrees) B C 2. Calculate the electric field 20 cm inward from charge A towards charge B if the total distance between them is 45cm and charge A is 5.8X10*C and Charge B 9.2X10*C
