There is a mine of depth about \( 3.0 \,\text{km} \). Conditions prevailing in this mine as compared to those at the surface of earth are
There is a mine of depth about \( 3.0 \,\text{km} \). Conditions prevailing in this mine as compared to those at the surface of earth are
Show Hint
Inside Earth, gravity decreases linearly with depth.

- higher air pressure, lower acceleration due to gravity
- higher air pressure, higher acceleration due to gravity
- lower air pressure, higher acceleration due to gravity
- lower air pressure, lower acceleration due to gravity
- same air pressure and acceleration due to gravity
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Pressure increases with depth, gravity decreases.
Step 1: Air pressure.
Deeper → more overlying air → higher pressure.
Step 2: Gravity.
Inside Earth: \[ g \propto r \Rightarrow \text{decreases with depth} \]
Step 1: Air pressure.
Deeper → more overlying air → higher pressure.
Step 2: Gravity.
Inside Earth: \[ g \propto r \Rightarrow \text{decreases with depth} \]
