Two very long straight parallel wires carry steady currents I and 1 The distance between the wires 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 v is perpendicular to this plane The magnitude of the force due to the magnetic field acting on the charge at this instant is A Holqv 2nd B A particle with charge Q and mass m enters a magnetic field of magnitude B 9 Hlqv C nd 2 Jqv D nd Zero
