An infinitely long straight conductor carries a current of `` 5\, A `` as shown. An electron is moving with a speed of `` 10^{5} m / s `` parallel to the conductor. The perpendicular distance between the electron and the conductor is `` 20\, cm `` at an instant. Calculate the magnitude of the force experienced by the electron at that instant.

(A) `` 4 \times 10^{-20} N ``
(B) `` 8 \pi \times 10^{-20} N ``
(C) `` 4 \pi \times 10^{-20} N ``
(D) `` 8 \times 10^{-20} N ``
