At least in the Newtonian approximation (excellent for most situations) you can just take the integral of (1/r2) divided by the rod length to get the inverse square of the effective average distance.If the distance from the central mass to the middle of the rod is r and the length of the rod is b, I get that the point you're looking for is at distance
r(1-(b2/4r2))1/2 from the central mass. If b is much less the r, then the point is shifted down ~b2/8r from the middle of the rod.<r, it's="" shifted="" down by="" ~b2="" 8r="" from="" the="" middle="" of="" rod.=""
