NEET Physics (general) Assertion Reason Question

Type: Assertion Reason-assertion-Medium-Class 11

Assertion (A): The elastic limit for typical rocks is crucial in determining the maximum height of a mountain. | Reason (R): Beyond the elastic limit, rocks will experience irreversible deformation, impacting mountain stability.

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 elastic limit determines the maximum stress rocks can withstand without permanent deformation, as calculated for mountain height using hρg = 30 × 10^7 N/m² in the NCERT context.
