Y,K, eta represent the Young's modulus, ...

`Y,K, eta` represent the Young's modulus, bulk modulus and rigidily modulus for a body respectively. If rigidity modulus is twice the Bulk Modulus, then,

A

`Y = 5K//18`

B

`Y = 5eta//9`

C

`Y = 9K//5`

D

`Y = 18K//5`

Text Solution

Verified by Experts

The correct Answer is:
D
`(9)/(Y) = (1)/(K) + (3)/(eta)`
