NEET Physics (general) MCQ Question
Type: MCQ-numerical-Easy-Class 11
A typical rock has an elastic limit of 30 × 10^7 N/m². If the density of the rock is 3 × 10^3 kg/m³, what is the maximum height (h) of the rock formation to remain within elastic limit under its own weight?
A
10 km
B
5 km
C
15 km
D
20 km
Correct Answer
Option A
Detailed Explanation
Using the formula hρg = elastic limit, where ρ = 3 × 10^3 kg/m³ and g = 10 m/s², solving for h gives h = 10 km.
