1. Consider two in contact spherical objects with 200mm diameter. If the density p of the spherical object is 7,800kg/m³, at what distance r measured from the center of earth will the force of mutual attraction between the contacting spheres be equal to the force exerted by the earth on one of the spheres? 3x10-11 N. ME = 5.9742X10² kg G=6.673x10-11 N
