Physics-Acceleration due to Gravity

NEET Physics Acceleration due to Gravity MCQ Question

Type: MCQ-numerical-Hard-Class 11

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?

A

g(1 - 2h/R_E)

B

g(1 + h/R_E)

C

g(1 - h/R_E)^2

D

g(1 - h^2/R_E^2)

Correct Answer

Option A

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.
