3. Red blood cells can be modeled as spheres of 7.33 µm diameter with -2.55x10-12 C excess charge uniformly distributed over the surface. Find the electric field at the following locations, with radially outward defined as the positive direction and radially inward defined as the negative direction. (a) What is the vector electric field inside the cell at a distance of 3.10 um from the center? (b) What is the vector electric field just outside the surface of the cell?
