Magnetic field due to a current element (as length is relatively very small, we can assume it as a current element) = $\mu /4\pi$ X idlsin $\theta$ /r²
For point A, $\theta$ = 90

For point B, tan $\theta$ = 5/14. Find $\theta$ . Use it in the formula.

For Point C, $\theta$ = 180. Hence sin $\theta$ = 0. So, here force is zero.
