Force Acting on Moving Charges: Practice Problem & Solution

Two very long straight parallel wires carry steady currents i and 2i in opposite directions. The distance between the wires is d. At a certain instant of time a point charge q is at a point equidistant from the two wires in the plane of the wires. Its instantaneous velocity \(\overrightarrow{v}\) is perpendicular to this plane. The magnitude of the force due to the magnetic field acting on the charge at this instant is :
\[\frac{\mu_{0}iqv}{2\pi d}\]
\[\frac{\mu_{0}iqv}{\pi d}\]
\[\frac{3\mu_{0}iqv}{2\pi d}\]
Zero
