  1. Correct Answer – D
    `C^(*):barC:C=sqrt((2RT)/(M)) = sqrt((8RT)/(piM)) = sqrt((3RT)/(M))`
    `= sqrt(2) : sqrt((8)/(3.142)) : sqrt(3)`
    `1:1.128:1.225`

  1. Correct Answer – A
    `overset(.)(C) : bar(C) : C = sqrt((2RT)/(m)) : sqrt((8RT)/(pi m)) : sqrt((3RT)/(m))`
    `= sqrt2 : sqrt((8)/(pi)) : sqrt3`
    `= 1.414 : 1.596 : 1.732`
    `= 1 : 1.128 : 1.225`

  1. Correct Answer – D
    `C^(**)=sqrt((2RT)/(M)), bar(C )=sqrt((8RT)/(piM)),C=sqrt((3RT)/(M))`
    `:. C^(**):bar(C ):C=sqrt((8)/(pi)):sqrt(3)=1:sqrt((4)/(pi)):sqrt((3)/(2))`
    `=1:1.128:1.225`
