A tiny sphere of mass 7.70 mg and charge −2.80 nC is initially at a distance of 1.64 μm from a fixed charge of +8.69 nC. (a) If the 7.70-mg sphere is released from rest, find its kinetic energy when it is 0.500 μm from the fixed charge.

terd muffin is the correct answer

1/0.14nm = 10^10/1.4 a lot

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

pe = weightxheight = 2000x1000=2,000,000joules
