Suppose the Sun's gravity were switched off. The planets would leave their orbits and fly away in straight lines as described by Newton's first law. (Assume the mass of the sun is 1.99 x 1030 kg, the orbital radius of Venus is 1.08 x 1011 m, and the orbital radius of Uranus is 2.87 x 1012 m.) (a) Would Venus ever be farther from the Sun than Uranus? O Yes O No (b) If so, find how long it would take for Venus to achieve this passage. (If not possible, enter IMPOSSIBLE.) :lvr
