Mountain pull. A large mountain can slightly affect the direction of "down" as determined by a plumb line. Assume that we can model a mountain as a sphere of radius R = 1.80 km and density (mass per unit volume) 2.6 x 10^3 kg//m^3. Assume also that we hang a 0.50 m plumb line at a distance of 3R from the sphere's center and such that the sphere pulls horizontally on the lower end. How far would the lower end move toward the sphere? |
