1.	The magnetic susceptibility of a metrial of a rod is 299. Permeatbility of vaccum `mu_(0)`A. `3771xx10^(-7)Hm^(-1)`B. `3771xx10^(-5)Hm^(-1)`C. `3770xx10^(-6)Hm^(-1)`D. `3771xx10^(-8)Hm^(-1)`
Answer» Correct Answer - A `"The given" chi_(m)=299` `and " " mu_(0)=4pixx10^(-7)Hm,mu=?` `"We know that", mu=mu_(0)(1+chi_(m))` `therefore " " 4pixx10^(-7)(1+299) Rightarrow =4xx(22)/(7)xx10^(-7)xx300` `" " =(2.6400)/(7)xx10^(-7)=3771.4xx10^(-7)Hm^(-1)or ` `" "cong3771xx10^(-7)Hm^(-1)`
