| ### Statement | |||
| − | $2.6.12.$ | ||
| + | $2.6.12.$ Determine the radius of the asteroid's circular orbit if the angular velocity of its revolution around the Sun is w, and the mass of the Sun is m. | ||
| ### Solution | |||
| For a circular orbit, the gravitational force provides the centripetal force:\ | |||
