Shows a metallic wire of resistance `0.20 Omega` sliding on a horizontal, U shaped metallic rail The separation between the parallel arms is 20 cm. jAn electric current of `2.0 mu A` passes through the wire when it is slid at a rate of `20cm s ^(-1)`. If the horizontal component of the earth's magnetic field is `3.0 X 10^(-5)` T, calculate the dip at the place.
