Question

Ceres is the smallest dwarf planet in the solar system, with a mass of 8.96e20 kg and a radius of 4.76e5 m. Pluto is the largest dwarf planet in the solar system with a mass of 1.31e22 kg and a radius of 1.19e6 m. What is the gravitational field near the surface of Ceres?

Answer 1

To calculate the gravitational field near the surface of Ceres, use the universal gravitational constant, Ceres's mass, and Ceres's radius in the formula g = G * M / r^2.

Step-by-step explanation:

To find the gravitational field near the surface of Ceres, we can use the formula for acceleration due to gravity, which is g = G * M / r2, where G is the universal gravitational constant (6.674×10−12 N(m/kg)2), M is the mass of the body (in this case, Ceres with a mass of 8.96×1020 kg), and r is the radius of the body (for Ceres, 4.76×105 m). After substituting the given values and calculating, you get the gravitational field strength near the surface of Ceres.
