A conductive sphere with a radius of 25 cm and a surface charge density of 6 micro C/m is centered on the y axis at y=1.

A conductive sphere with a radius of 25 cm and a surface charge density of 6 micro C/m is centered on the y axis at y=1.5m. A second conductive sphere with a radius of 10 cm and a surface charge density of 6 micro C/m is centered on the y axis at y=0m. What is the magnitude and direction of the electric field at y=1.00 m?
