As shown in the figure, a metallic rod of linear density 0.45 kg m-1 is lying horizontally on a smooth incline plane which makes an angle of 45° with the horizontal. The minimum current flowing in the rod required to keep it stationary, when 0.15 T magnetic field is acting on it in the vertical upward direction, will be :
{Use g = 10 m/s2}
(A) 30 A
(B) 15 A
(C) 10 A
(D) 3 A
