Bulk modulus of a material is `2.5xx10^(11)"dyne"//cm^(2)` and Poisson's ratio is 0.4. Then young's modulus for such material ios

A

`3xx10^(11)"dyne"//cm^(2)`

B

`4.5xx10^(11)"dyne"//cm^(2)`

C

`1.5xx10^(11)"dyne"//cm^(2)`

D

`6xx10^(11)"dyne"//cm^(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`y=3k(1-2sigma)`
`=3xx2.5 xx 10^(11) (1-2xx0.4)`
`=7.5xx10^(11) xx 0.2`
`=1.5xx10^(11)"dyne"//cm^(2)`.
