Question

A very small sphere with positive charge q=+6.00μC is released from rest at a point 1.30cm from a very long line of uniform linear charge density λ=+2.00μC/m.

Part A

What is the kinetic energy of the sphere when it is 4.80cm 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.
