The horizontal component of earth's magnetic field at a certain place is `3*0xx10^-5T` and the direction of the field is form the geographic south to the geographic north. A very long straight conductor is carrying a steady current of `1A`. What is the force per unit length on it when it is placed on a horizontal table and the diection of the current is (a) east to west (b) south to north?
