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

Official answer
From NTA’s final answer key for this paper.
