A 235 km long power line experiences a downward pull of 2.50 N due to the interaction of the earth's magnetic field and the current carried by the wire. If the strength of the earth's magnetic field is 4.50 x 10-5 T, then what is the current in the line? Assume the line is at right angles to the earth's magnetic field. Select one: a. b. O c O d. 2.87 x 10-³ A 5.62 x 10² A 2.36 x 10-¹ A 4.23 A
