Answer all the question please. 1.36 will answer 1.42 thanks

- Two long, straight wires, one above the other, are separated by a distance 2a and a: parallel to the x-axis. Let the +y - axis b in the plane of the wires in the direction frc the lower wire to the upper wire. Each wire carries current I in the +x-direction. Wh are the magnitude and direction of the net magnetic field of the two wires at a point ir the plane of the wires (a) midway between them; (b) at a distance a above the upper wire; (c) at a distance a below the lower 1.36 -. Given two vectors A=4.00i^+7.00j and B=5.00i^2.00j^, (a) find the magnitude of each vector; (b) use unit vectors to write an expression for the vector difference AB; and (c) find the magnitude and direction of the vector difference AB. (d) In a vector diagram show A,B, and AB, and show that your diagram agrees qualitatively with your answer to part (c). 1.42 - Find the vector product AB (expressed in unit vectors) of the two vectors given in Exercise 1.36. What is the magnitude of the vector product? - CP A 150g ball containing 4.00108 excess electrons is dropped into a 125m vertical shaft. At the bottom of the shaft, the ball suddenly enters a uniform horizontal magnetic field that has magnitude 0.250T and direction from east In a Hall-effect experiment, is it possible that no transverse potential difference will be observed? Under what circumstances might this happen? to west. If air resistance is negligibly small, find the magnitude and direction of the force that this magnetic field exerts on the ball just as it enters the field. - Two long, straight wires, one above the other, are separated by a distance 2a and a: parallel to the x-axis.
