### How to get the values of y coordinate for equidistant values of x coordinate from a plot obtained by numerically solving a differential equation?

I need to find the value of $V[r_{*}]$ at equidistant values of $r_{*}$ (say $r_{*}$ goes from 0 to 10 in steps of 0.1) from the graph. Is it possible? I used the code ...
