Q. The figure below depicts a long wire carrying a current coming out of the plane of the paper. A charge q at a distance x from it is moving towards it with speed v and experiences a magnetic force of magnitude F. If the distance of the charge from the wire were 2x (and all other conditions remaining the same) then the force would be
