NEET Physics Acceleration due to Gravity MCQ Question
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?
g - (2gh/RE)
g - (gh/RE)
g + (2gh/RE)
g + (gh/RE)
Correct Answer
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).
