Physics-Acceleration due to Gravity

NEET Physics Acceleration due to Gravity Assertion Reason Question

Type: Assertion Reason-assertion-Hard-Class 11

Assertion (A): The acceleration due to gravity decreases as one moves below the Earth's surface. | Reason (R): The gravitational force at a depth d is given by F(d) = (G * M_E * m * (R_E - d)) / R_E^3.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false.

Correct Answer

Option A

Detailed Explanation

The NCERT context explains that as we go below the Earth's surface, the acceleration due to gravity decreases due to the reduction in effective mass contributing to gravitational force, which is captured in the formula for F(d).
