If the Young's modulus of the material is 3 times its modulus of rigidity, then its volume elasticity will be

A

Zero

B

Infinity

C

`2 xx 10^(10) N//m^(2)`

D

`3 xx 10^(10) N//m^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`Y= 2 eta (1+ sigma) rArr 3 eta= 2 eta (1 + sigma) rArr sigma= (1)/(2)`
Now, `Y = 3B(1- 2 sigma) rArr B= (Y)/(3(1- 2 sigma)) =oo`
