A straight conducting rod of length `30 cm` and having a resistance of `0.2` ohm is allowed to slide over two parallel thick metallic rails with uniform velocity of `0.2 m//s` as shown in the figure. The rails are situated in a horizontal plane if the horizontal component of earth's magnetic field is `0.3 xx 10^(-4)T` and a steady current of `3 muA` is induced through the rod. The angle of dip will be:
