Part 2 X Your answer is incorrect. The Sun has a mass of 2 x 1030 kg and the distance from the Sun to Mars is 2.3 x 10¹1 m. If Mars had no mass, there would still be a small gravitational force on an object near Mars's surface, due only to the Sun. What would be the value of g on (massless) Mars, due to the gravitational force of the Sun? Assume that Mars's radius is negligible compared to the distance between the Sun and Mars. g= i 0.00248 eTextbook and Media Hint A Save for Later This problem is equivalent to assuming that there is a spherical surface surrounding the Sun, and finding the value of g on that surface. The radius of the surface is the same as the distance from Sun to the other body. OCT 20 N/kg O Assistance Used tv N Attempts: 1 of 4 used Submit Answer
