A conductor carrying a current I = 14.6 A is directed along the positive x axis and perpendicular to a uniform magnetic field. A magnetic force per unit length of 0.119 N/m acts on the conductor in the negative y direction.

(a) Determine the magnitude of the magnetic field in the region through which the current passes. T
(b) Determine the direction of the magnetic field in the region through which the current passes.+x direction −x direction +y direction −y direction +z direction −z direction

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?
