On a smooth inclined plane at `30^@` with the horizontal a thin current carrying metallic rod is placed parallel to the horizontal ground. The plane is located in a uniform magnetic field of `0*15tesla` in the vertical direction. For what value of current can the rod ramain stationary? The mass per unit length of rod is `0*30kgm^-1`.
