NEET Solved Paper 2017 Question 32
Question: The bulk modulus of a spherical object is ‘B’. If it is subjected to uniform pressure ‘p’ , the fractional decrease in radius is
Options:
A) $ \frac{\rho }{3B} $
B) $ \frac{\rho }{B} $
C) $ \frac{B}{3p} $
D) $ \frac{3p}{B} $
Show Answer
Answer:
Correct Answer: A
Solution:
- $ B=\frac{p}{( \frac{\Delta V}{V} )} $ $ \frac{\Delta V}{V}=\frac{p}{B} $ $ 3\frac{\Delta r}{r}=\frac{p}{B} $ $ \frac{\Delta r}{r}=\frac{p}{3B} $
