Currents of a 10 ampere and 2 ampere are passed through two parallel thin wires $$A$$ and $$B$$ respectively in opposite directions. Wire $$A$$ is infinitely long and the length of the wire $$B$$ is 2 m. The force acting on the conductor $$B$$, which is situated at 10 cm distance from $$A$$ will be

A

$$8 \times 10^{-5}$$ N

B

$$5 \times 10^{-5}$$ N

C

$$8\pi \times 10^{-7}$$ N

D

$$4\pi \times 10^{-7}$$ N
