Lesson: The Gravitational Field Inside PlanetsPhysics
In this lesson, we will learn how to calculate the magnitude of the acceleration due to gravity at a point inside of a planet.
Sample Question Videos
Which of the following relations shows how the local acceleration due to gravity, , at any point outside or inside a planet varies with the density of the planet, , if the planet has a constant density throughout?
What is the acceleration due to gravity at a distance of from Earth’s center of mass? Assume that Earth is a perfect sphere with a radius and a constant density of 5,510 kg/m3. Give your answer to two decimal places.
What is the acceleration due to gravity at the center of Earth?
