Due to symmetry magnetic field at point p will be only due upper wire part of length L

So B = (u_oI/4 $\pi$ a)(sin $\Theta _{1}$ + sin $\Theta _{2}$ )

B = (10^-7*5/0.1)( $1/\sqrt{5} + 1/\sqrt{5}$ )

B = 8.92*10^-6 T

Hope it clears.

Four long co-axial thin walled cylindrical conductor A, B, C and D have radii R. 2R 3R and 4R respectively. A and C carry current I and 31 respectively to plane of paper on the other hand, B and D carry and 41 respectively outward to plane of paper. Then 21
