A metallic rod of mass per unit length 0.5 kg `m^(-1)` is lying horizontally on a smooth inclined plane which makes an anlge 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

A metallic rod of linear density is 0.25 kg m^(-1) is lylong horizontally on a smooth inclined plane which makes an angle of 45^(@) with the horizontal. The rod is not allowed to slide down by flowing a current through it when a magnetic field of strength 0.25 T is acting on it in the vertical direction. Calculates the electric current flowing in the rod to keep it stationary .

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 uniform magnetic field induction B is applied vertically downwards. If the current through the rod is 1*73ampere , the value of B for which the rod remains stationary on the inclined plane is
