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`.

On a smooth plane inclined at 30^(@) with the horizontal, a thin current carrying metallic rod is placed parallel to the horizontal ground. The plane is in a uniform magnetic field of 0.15T alon the vertical direction. For what value of current can the rod remain stationary ? the mass per unit lenght of the rod is 0.30 kg/m.

A horizontal rod of mass 10g and length 10cm is placed on a smooth plane inclined at an angle of 60^@ with the horizontal with the length of the rod parallel to the edge of the inclined plane.

A metallic rod of mass per unit length 0.5kgm^(-1) is lying horizontally on a smooth inclined plane which makes an angle of 30^(@) with the horizontal. The rod is not allowed to slide down by flowing a current through it when a magnetic field of induction 0.25 T is acting on it in the vertical direction. The current flowing in the rod to keep it stationary is.
