Enter the expression asin(x)+15asin(x)+15 , where asin(x)asin(x) is the inverse sine function. Alternatively, you may enter the inverse sine function in either of the following forms, which are also accepted: arcsin(x)arcsin(x) or sin−1(x)sin−1(x).

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.
