BITSAT 2023 | Elasticity Question 1 | Physics

For a constant hydraulic stress on an object, the fractional change in the object's volume $$(\Delta V / V)$$ and its bulk modulus $$B$$ are related as

$$\frac{\Delta V}{V} \propto B$$

$$\frac{\Delta V}{V} \propto B^2$$

$$\frac{\Delta V}{V} \propto \frac{1}{B}$$

$$\frac{\Delta V}{V} \propto \frac{1}{B^2}$$

For a constant hydraulic stress on an object, the fractional change in the object's volume $$\left( {{{\Delta V} \over V}} \right)$$ and its bulk modulus B are related as

$${{\Delta V} \over V} \propto B$$

$${{\Delta V} \over V} \propto {B^2}$$

$${{\Delta V} \over V} \propto {1 \over B}$$

$${{\Delta V} \over V} \propto {1 \over {{B^2}}}$$
