The figure above shows a metal bar that is supported by two sections of afixed, conducting U-shaped horizontal rail. The rod and rail are located in aregion of magnetic field B directed into the page. The bar is moving to theright at a constant speed. Which of the following is true of the horizontalforces acting on the bar? *XXXX X X₁ XX X XX XX X XXTop ViewThere are no forces.XXXXXXXXThere is only a magnetic force.There is only an external applied force.There is both a magnetic force and an external applied force.Nothing can be said about the forces without knowing the magnitude of the magneticfield.
