A) \[1.2\,J{{T}^{-1}}\]
B) \[2.4\,J\,{{T}^{-1}}\]
C) \[3.0\text{ }J\text{ }{{T}^{-1}}\]
D) \[3.6\text{ }J\text{ }{{T}^{-1}}\]
Correct Answer: D
Solution :
(d) \[3.6\text{ }J\text{ }{{T}^{-1}}\] Here,\[N=3000,\text{ }A=2\times {{10}^{-4}}{{m}^{2}},l=6A\] \[\therefore \,\,\,M=NlA=3000\times 6\times 2\times {{10}^{-4}}=3.6\text{ }J{{T}^{-1}}\]You need to login to perform this action.
