    Electricity with conservation of energy involved.

    A tiny sphere of mass 7.70 µg and charge −2.80 nC is initially at a distance of 1.74 µm from a fixed charge of +9.25 nC. (a) If the 7.70-µg sphere is released from rest, find its kinetic energy when it is 0.500 µm from the fixed charge. (b) If the 7.70-µg sphere is released from rest, find...
