Along, straight wire with 5 a current flowing through it produces magnetic field strength 2 t at its surface. if the wire has a radius r, where within the wire is the field strength equal to 51 % of the field strength at the surface of the wire? assume that the current density is uniform throughout the wire. (μ 0 = 4π × 10-7 t · m/a)

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
