Q141 / 160 · WBJEE 2011 · Physics

A material has Poisson's ratio 0.50. If a uniform rod of it suffers a longitudinal strain of \(2 \times 10^{-3}\), then the percentage change in volume is

A
0.6
B
0.4
C
0.2
Correct answer
D
zero

Solution

Hints : Poisson's ratio is 0.5 so there is no change in volume

Hence, the correct answer is option: 'D'.
