Three small spheres are placed at fixed points along the xaxis, whose positive direction points towards the right.
Sphere A is at x = 23.0 cm, with a charge of 10.00 ìC.
Sphere B is at x = 55.0 cm, with a charge of 2.00 ìC.
Sphere C is at x = 57.0 cm, with a charge of 9.00 ìC.
(A)If Sphere B is removed. Give the xcoordinate of the point on the xaxis where the field due to spheres A and C is zero? (answer 40.4 cm)

sorry it was suppose to read with a charge of 10 microCoulombs for sphere A, 2 microCoulombs for sphere B and 9 microCoulombs for sphere C.
