JEE MAIN - Physics (2022 - 24th June Morning Shift - No. 1)
The bulk modulus of a liquid is 3 $$\times$$ 1010 Nm$$-$$2. The pressure required to reduce the volume of liquid by 2% is :
3 $$\times$$ 108 Nm$$-$$2
9 $$\times$$ 108 Nm$$-$$2
6 $$\times$$ 108 Nm$$-$$2
12 $$\times$$ 108 Nm$$-$$2
Explanation
$$\because$$ $$B = {{\Delta P} \over {\left( { - {{\Delta V} \over V}} \right)}}$$
$$ \Rightarrow \Delta P = 3 \times {10^{10}} \times (0.02)$$
$$ = 6 \times {10^8}$$ N/m2
