NEET Physics Acceleration due to Gravity MCQ Question
If the acceleration due to gravity at the surface of the Earth is denoted by g, what will be the acceleration due to gravity at a height h above the Earth's surface where h is much smaller than the Earth's radius R_E?
g(1 - 2h/R_E)
g(1 + h/R_E)
g(1 - h/R_E)^2
g(1 - h^2/R_E^2)
Correct Answer
Detailed Explanation
The acceleration due to gravity at a height h above the Earth's surface is given by g(h) ≈ g(1 - 2h/R_E) for small heights h, as per the expansion using the binomial theorem.
