A pair of stationary and infinitely long bent wires are placed in the `x-y` plane as shown in figure
. The wires carry currents of 10A each as shown. The segments L and M are along the x-axis. The segments P and Q are parallel to the y-axis such that OS = OR = 0.02m. Find magnitude and direction of the magnetic induction at the origin O.

Options

A. `100 Wb m^-2` vertically upward
B. `10^-4 Wb m^-2` vertically downward
C. `10^-4 Wb m^-2` vertically upward
D. `0.01 Wb m^-2` vertically downward.
