The relation between Y. `eta` and B is

Options

A. `(1)/(Y) = (1)/(3 eta) + (1)/(9B)`
B. `(9)/(Y) = (1)/(eta) + ( 3)/(B)`
C. `(1)/(eta) = (1)/(B) + (1)/(Y)`
D. `(9)/(Y) = (3)/(eta) + (1)/(B)`

Answer

D

Explanation

The relation between Y, `eta` and B is `(9)/(Y) = (1)/(B) + (3)/(eta)` where Y is Young.s modulus, B is bulk modulus and `eta` modulus of rigidity.
