A) \[8.6\times {{10}^{-5}}N\]
B) \[6.6\times {{10}^{-5}}N\]
C) \[7.6\times {{10}^{-5}}N\]
D) \[9.6\times {{10}^{-5}}N\]
Correct Answer: D
Solution :
(d) \[9.6\times {{10}^{-5}}N\] Here, \[{{l}_{1}}=2\,\,A,{{l}_{2}}=12\,\,A,\,d=100\,mm=0.1\,m,l=2m\] Now total force on length i of small conductor \[F=\frac{{{\mu }_{0}}}{4\pi }\times \frac{2{{l}_{1}}{{l}_{2}}}{d}l=\frac{{{10}^{-7}}\times 2\times 2\times 12\times 2}{0.1}\] \[=9.6\times {{10}^{-5}}N\]You need to login to perform this action.
