a -58 nC charge is distributed uniformly along the x-axis from x = -1.3 m to x = 3.4 m. Consider a point at y = 2.2 m on the y-axis.
a) what is the x-component of the electric field at the point?
b) what is the y-component of the electric field at the point?
c) what is the total magnitude of the electric field at the point?
