A) \[1.4\times {{10}^{-4}}N\]towards the right
B) \[1.4\times {{10}^{-4}}N\]towards the left
C) \[2.6\times {{10}^{-4}}N\]towards the right
D) \[2.6\times {{10}^{-4}}N\]towards the left
Correct Answer: A
Solution :
[a] \[F=\frac{4\pi \times {{10}^{-7}}\times 20\times 10\times 10\times {{10}^{-2}}}{2\pi \times 2\times {{10}^{-2}}}\] \[-\frac{4\pi \times {{10}^{-7}}\times 10\times 30\times 10\times {{10}^{-2}}}{2\pi \times 10\times {{10}^{-2}}}\] \[=1.4\times {{10}^{-4}}N\]towards right.
