A) Repulsive force of \[{{10}^{-4}}N/m\]
B) Attractive force of \[{{10}^{-4}}N/m\]
C) Repulsive force of \[2\pi \times {{10}^{-5}}N/m\]
D) Attractive force of \[2\pi \times {{10}^{-5}}N/m\]
Correct Answer: A
Solution :
\[F=\frac{{{\mu }_{0}}}{4\pi }\frac{2{{i}_{1}}{{i}_{2}}}{r}={{10}^{-7}}\times \frac{2\times 10\times 5}{0.1}={{10}^{-4}}N\](Repulsive)You need to login to perform this action.
