A horizontal straight wire 10 m long extending from east to west

A horizontal straight wire 10 m long extending from east to west is falling with a speed of 5.0 ms, at right angles to the horizontal component of the earth's magnetic field, 0.30 10* Wb m. What is the instantaneous value of the emf induced in the wire? What is the direction of the emf? Which end of the wire is at the higher electrical potential?
