` sigma _|eta ` तथा K के मध्य सही संबंध है

Options

A. ` sigma =(3K+2eta)/( 6K + 2eta ) `
B. ` sigma =( 6K + 2eta )/( 3K - 2eta ) `
C. ` sigma = ( 3K+2eta )/( 6K - 2eta )`
D. ` sigma =(3K+2eta )/( 6K -2eta)`

Answer

D

Explanation

`Y = 3K( 1-2sigma ) " " ...(i)`
` " " y=2eta (1+ sigma ) " "...(ii)`
समय (i ) व् (ii ) से
` " " 3K (1- 2sigma ) = 2eta (1+sigma) `
या ` " " 3K -6 sigma K= 2eta +2eta sigma`
या ` " " 6K sigma +2eta sigma =3K -2eta`
`sigma (6K +2eta ) =(3K-2eta ) `
या ` " " sigma =(3K-2eta )/( 6K +2eta )`
