A point charge of +10 °C is at (+3 m, O m) on the x-axis and a point charge of +10 C is at (-3 m, O m).

1) Determine the work required to assemble this charge
distribution

2) Find the magnitude of the electric field at a point (0,+3
m) on the y-axis.

3) A charge q - +1°C is placed at a point (0, +3 m) on the y-axis.
Find the magnitude of the force on the 1C charge.
