AMPS AND DETERMININ DISTANCE, urgent plz help Crossed wires (a) Two long current-carrying wires cross at an angle of 37° ("theta" is half of this) as shown in the figure below. The magnitude of the current is the same in each wire, I = 177 A. A wood mouse is running along the dashed line midway between the wires towards the point where the wires cross. The mouse turns back at point P, some distance x from the wire crossing point, because the magnetic field strength reaches an unbearable 8.7 mT. Determine the distance x (in cm). Okay I am completely stuffed on how to begin this problem, I dont really know where to start... maybe I could be given some help as how to relate distance to the B and I! okay wats confusin me... is how to find the force in order to find the length... I was thinkin bout usin, F=IlBsin(theta) But yeah Id really like a hint please!
