7. A very long line of charge, with uniform positive charge per unit length l, is held fixed b) If the positive point charge Q is suddenly released, it will accelerate away from the line charge. Will the acceleration be constant? in place. Located a distance D from the line charge, and also fixed in place, is a point mass m with positive charge Q. c) How fast will the point charge be going by the time it has reached a distance 5D from the line charge? * a) Use Gauss's Law to calculate the strength of the electric field created by the line charge, at any distance r from the line charge.
