A small metal sphere, carrying a net charge of q1= -3.10 micro C is held in a stationary position by insulating supports. A second small metal sphere, with a net charge of q2= -7.90 micro C and mass 1.90g is projected toward q1. When the two spheres are 0.800m apart, q2 is moving toward q1 with speed 22.0m/s. Assume the two spheres can be treated as point charges. You can ignore the force of gravity. A. What is the speed...

Two small spheres, A and B, are separated by a distance of 1.5 m as shown below. Sphere A has a charge of 3 μC and Sphere B has a charge of -6 μC. (The prefix \"μ\" means \"micro\" which is a \"millionth.\" So, 1 microCoulomb = one-millionth of a Coulomb = 10-6 C.) Sphere C, is now moved to a new position that is directly above Sphere A. The distance between A and C is still half the distance...
