An insulating sphere of radius a, centered at the origin, has a uniform volume charge densityrho.
a spherical cavity is excised from the inside of the sphere. the cavity has radius \frac{a}{4} and is centered at position h_vec, where |\vec{h}|< \frac34 a , so that the entire cavity is contained within thelarger sphere. find the electric field inside the cavity.
express your answer as a vector interms of any or all of rho, epsilon_0, r_vec, and h_vec.
