The susceptibiltiy of magnesium at 300 k is `2.4 xx10^(-5)` at what temperature will the susceptibility increase to `3.6xx10^(-5)`

Explanation

Given : `chi_(m_(1))=2.4xx10^(-5),T_(1)=300" K",chi_(m_(2))=3.6xx10^(-5)`.
`because" "chi_(m)prop(1)/(T)`
`implies" "(chi_(m_(1)))/(chi_(m_(2)))=(T_(2))/(T_(1))`
`implies" "(2.4xx10^(-5))/(3.6xx10^(-5))=(T_(2))/(300)`
`implies" "T_(2)=200"K."`
