NEET Physics (general) MCQ Question
Type: MCQ-numerical-Hard-Class 11
Given the elastic limit for a typical rock is 30 × 10^7 N/m² and its density is 3 × 10^3 kg/m³, what is the maximum height of a mountain composed of this rock type before reaching its elastic limit?
A
10 km
B
15 km
C
5 km
D
20 km
Correct Answer
Option A
Detailed Explanation
The height is calculated by equating the elastic limit to hρg, yielding h = 30 × 10^7 N/m² / (3 × 10^3 kg/m³ × 10 m/s²) = 10 km, indicating the maximum height before the rock reaches its elastic limit.
