NEET Physics Acceleration due to Gravity MCQ Question

Type: MCQ-numerical-Medium-Class 11

If the acceleration due to gravity on the surface of Earth is g, what is the approximate acceleration due to gravity at a height h << RE above the Earth's surface?

A

g - (2gh/RE)

B

g - (gh/RE)

C

g + (2gh/RE)

D

g + (gh/RE)

Correct Answer

Option A

Detailed Explanation

Using the binomial expression, the acceleration due to gravity at a small height h above the Earth's surface decreases by a factor of (1 - 2h/RE) as shown in Eq. (7.15).
