(a) Linearize the graph. If necessary, compute different powers of variables and plot until you get a straight line. (b) Determine the equation of the line obtained. Indicate the value of n, k, and other constants or intercepts present in the graph. a.) The data below shows how the electric field (E) due to a point charge varies with distance (r).
