With a mean radius of 24,622 19 km and a mass of 1.02431026 kg, Neptune is the fourth largest planet in the solar system. As gravity pulls objects toward the ground, it causes them to accelerate at a rate of 9.8 m/s 2. If the magnitude of the gravitational acceleration on the surface of the planet is 6.1 m/s^2, what is the radius of the planet. Uranus' gravitational pull of 8.69 m/s2 is very close to that of Venus. And you can verify that the units work out. 6 How is the gravity of a planet related to its size? . Calculate the image distance. Please select the most appropriate category to facilitate processing of your request. {\displaystyle r} The accepted value of the acceleration due to gravity is 9.81 m/s 2 .
