MHT CET 2023 Physics question
A mine is located at depth below earth's surface. The acceleration due to gravity at that depth in mine is (R = radius of earth, g = acceleration due to gravity)
Answer: (C)
Solution
Below the surface the acceleration due to gravity decreases linearly with depth: . With , , option (c). This is because only the inner sphere of radius attracts the body, and its mass is
