1 A fixed horizontal wire carries a current of 200 A. Another wire having a mass per unit length 10-kg/m is placed below the first wire at a distance of 2 cm and parallel to it. How much current must be passed through the second wire if it floats in air without any support? What should be the direction of current in it (a)25A (direction of current is same to first wire) (b)25A (direction of current is opposite to first wire) (c)49 A (direction of current is same to first wire) (d)49 A (direction of current is opposite to first wire)
