Challenge Problems
Push your limits with challenges.
Question 1
A satellite is orbiting Earth at a height where gravitational acceleration is 8.7 m/s². Calculate the height of the satellite above Earth's surface. Use g(h) = g(1 - (h/R_E)).
💡 Hint: Rearrange the equation to solve for height h.
Question 2
Explain why the gravitational force on an object at the center of the Earth is zero, considering Earth’s layers and gravitational principles.
💡 Hint: Use shell theorem to analyze mass distribution.
