10. Conservation of Energy / Gravitational Potential Energy / 문제 8
문제 8
A large hollow ball of outer radius R1 was put into space. Its inner radius is R2. The shell of the hollow ball of thickness R1-R2 is uniform in mass distribution and has a total mass of m. If another mass m' was placed at a distance of R (R > R1) away from the center of the hollow ball, calculate the gravitational potential energy of this mass m'.
