Q. The bulk modulus of a spherical object is 'B'. If it is subjected to uniform pressure 'p', the fractional decrease in radius is :
A) $\frac{p}{B}$
B) $\frac{B}{3p}$
C) $\frac{3p}{B}$
D) $\frac{p}{3B}$
Explanation
[Solution] $\Delta V/V = p/B$ and $\Delta V/V = 3\Delta r/r$, so $\Delta r/r = p/(3B)$. Answer (4).
