A spherical cavity is excised from the inside of the sphere. The cavity has radius a/4 and is centered at position ℎ→, where |ℎ→|<3a/4, so that the entire cavity is contained within the larger sphere. Find the electric field inside the cavity. trying to find as a vector in terms of any or all of ρ (Greek letter rho), ϵ0, r→, and h
