Question

A nonconducting sphere 1.9 m in diameter with its center on the x axis at x = 4 m carries a uniform volume charge of density ρ = 7.6 µC/m3. Surrounding the sphere is a spherical shell with a diameter of 3.8 m and a uniform surface charge density σ = -2.3 µC/m2. Calculate the magnitude and direction of the electric field at the following locations.

a) x = 4.9 m, y = 0
