Application +4 | -1
The Marina trench is located in the Pacific Ocean and at one place it is nearly eleven km\mathrm{km} beneath the surface of water. The water pressure at the bottom of the trench is about 1.1×108 Pa1.1 \times 10^8 \mathrm{~Pa}. A steel ball of initial volume 0.32 m30.32 \mathrm{~m}^3 is dropped into the ocean and falls to the bottom of the trench. What is the change in the volume of the ball when it reaches to the bottom?
View answer and explanation
Correct option: A
2.02×10−4 m32.02 \times 10^{-4 } \mathrm{~m}^3
Option A (2.02×10−4 m32.02 \times 10^{-4 } \mathrm{~m}^3) is correct because it is calculated using the bulk modulus formula with the given pressure, volume, and bulk modulus of steel.
