An insulating sphere of radius a,centered at the origin, has a uniform volume charge density ρρ. A spherical cavity is excised from the inside of the sphere.The cavity has radius a/4 and is centered at position h⃗ h→, where |h⃗ |<34a|h→|<34a, so that the entire cavity is contained within the larger sphere. Find the electric field inside the cavity. Express your answer as a vector in terms of any or all of ρρ, ϵ0ϵ0, r⃗ r→ and h⃗ h→.
