Physics-Acceleration due to Gravity

NEET Physics Acceleration due to Gravity MCQ Question

Type: MCQ-diagram based-Easy-Class 11

Consider a diagram where a point mass m is placed at a depth d inside the Earth. Which equation correctly describes the acceleration due to gravity at this depth?

Question diagram
A

g(d) = g(1 - d/R_E)

B

g(d) = g(1 + d/R_E)

C

g(d) = g(1 - 2d/R_E)

D

g(d) = g(1 + 2d/R_E)

Correct Answer

Option A

Detailed Explanation

The acceleration due to gravity at a depth d below the Earth's surface decreases by a factor (1 - d/R_E) as per the equation g(d) = g(1 - d/R_E).
