362644 Two long parallel conductors carry currents in opposite direction as shown. One conductor carries a current of 10\(A\) and the distance between the wires is \(d = 10\;cm\). Current \(I\) is adjusted so that the magnetic field at \(P\) which is at a distance of 5\(cm\) to the right of 10\(A\) current is zero.Value of \(I\) is

362645 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.
