A) Attract each other with a force of \[{{\mu }_{0}}{{i}^{2}}/(2\pi {{d}^{2}})\]
B) Repel each other with a force of \[{{\mu }_{0}}{{i}^{2}}/(2\pi {{d}^{2}})\]
C) Attract each other with a force of \[{{\mu }_{0}}{{i}^{2}}/(2\pi d)\]
D) Repel each other with a force of \[{{\mu }_{0}}{{i}^{2}}/(2\pi d)\]
Correct Answer: C
Solution :
\[\left( \frac{F}{l} \right)=\frac{{{\mu }_{0}}}{4\pi }.\frac{2{{i}_{1}}{{i}_{2}}}{a}\]Þ\[\left( \frac{F}{l} \right)=\frac{{{\mu }_{0}}}{4\pi }.\frac{2{{i}^{2}}}{d}=\frac{{{\mu }_{0}}{{i}^{2}}}{2\pi d}\] (Attractive)You need to login to perform this action.
