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

Options

A. zero
B. infinity
C. `2 xx 10^(10) Nm^(-2)`
D. `3 xx 10^(10) Nm^(-2)`

Answer

b

Explanation

`(3)/(eta) + (1)/(B) = (9)/(Y)`or `(1)/(B) = (9)/(y) - (3)/(eta)`
`implies (1)/(B) = (9)/(3 eta) - (3)/(eta) = 0 implies prp`
