A very small sphere with positive charge $$q=+6.00?\mathrm{C}$$ is released from rest at a point $$1.50\mathrm{cm}$$ from a very long line of uniform linear charge density $$?=+4.00?\mathrm{C}/\mathrm{m}$$. What is the kinetic energy of the sphere when it is $$4.10\mathrm{cm}$$ from the line of charge if the only force on it is the force exerted by the line of charge? Express your answer with the appropriate units.
