    Identical point charges q1 and q2 each have a positive charge +6.00 μC. Charge q1 is held fixed on the x-axis at x=+0.400 m, and q2 is held fixed on the x-axis at x=−0.400 m. A small sphere has charge Q=−0.200 μC and mass 12.0 g. The sphere is initially very far from the origin. It is released from rest and moves along the y-axis toward the origin. (a) As the sphere moves from very large y to y=0, how...
