A) 36 ´ 10?6 T
B) 72 ´ 10?6 T
C) 144 ´ 10?6 T
D) 288 ´ 10?6 T
Correct Answer: C
Solution :
\[\frac{{{T}_{A}}}{{{T}_{B}}}=\sqrt{\frac{{{({{B}_{H}})}_{B}}}{{{({{B}_{H}})}_{A}}}}\Rightarrow \frac{60/10}{60/20}=\sqrt{\frac{{{({{B}_{H}})}_{B}}}{36\times {{10}^{-6}}}}\] \[\Rightarrow {{({{B}_{H}})}_{B}}=144\times {{10}^{-6}}T\]You need to login to perform this action.
