NEET Physics Variation of g with Height and Depth MCQ Question
The acceleration due to gravity at a height 1 km above the Earth is the same as at a depth d below the surface of Earth. Then
d = 1 km
d = 3/2 km
d = 2 km
d = 1/2 km
Correct Answer
Detailed Explanation
The acceleration due to gravity decreases with height and increases with depth. Using the formula for gravity variation, g' = g(1 - 2h/R) for height and g' = g(¹⁻ d/R) for depth, equating them gives the depth.
