QUESTION:
Consider two iron spheres, each of diameter \(100 \mathrm{~mm}\), which are just touching. At what distance r from the center of the 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?
ANSWER:The force of gravity between two objects is given by F = G*m1*m2 / r^2, so the distance r can be calculated as r = sqrt(G * m1 * m2 / F), where F is th
