A) \[0.22\,J\,{{T}^{-1}}\]
B) \[0.32\,J\,{{T}^{-1}}\]
C) \[0.42\,J\,{{T}^{-1}}\]
D) \[0.52\,J\,{{T}^{-1}}\]
Correct Answer: C
Solution :
(c) \[0.42\,J\,{{T}^{-1}}\] Here, \[N=1000,\text{ }A=14\times {{10}^{-4}}{{m}^{2}},l=3A\] \[M=NlA=1000\times 3\times 14\times {{10}^{-4}}=0.42\text{ }J{{T}^{-1}}\]You need to login to perform this action.
