Suppose in (Figure 1) that x = 0.180 mm, and that the uniformly charged wire is only 6.10 mm long and extends along the y-axis from y= -3.60 mm to y = +2.50 mm. The total charge of the wire is Q = 2.74 μC. a) Calculate Ex and Ey at point P (give values in newtons per coulomb).b) Determine what the error would be if you simply used the result for a very long wire, E=λ/2πϵ0x . Express this error as (Ex−E)/E and Ey/E Express your answers as percentage to two significant figures
