The diagram shows the all of the forces acting on a body of mass m = 7.95 kg. the three forces have magnitudes f1 = 12.8 n, f2 = 29.3 n, and f3 = 13.3 n, with directions as indicted in the diagram, where θ = 28.8 degrees and the dashed line is parallel to the y axis write an expression for the x component of the acceleration in terms of the symbols in the problem statement

Along wire carrying a 4.2 a current perpendicular to the xy-plane intersects the x-axis at x=−1.7cm. a second, parallel wire carrying a 3.0 a current intersects the x-axis at x=+1.7cm. part a at what point on the x-axis is the magnetic field zero if the two currents are in the same direction? express your answer to two significant figures and include the appropriate units.
