A positive charge Q = 6400.00 C is uniformly distributed over the volume of a sphere of radius R =1.50 m. Assume a spherical cavity of radius R/2 is cut out of the solid sphere, the center of the cavity being a distance R/2 from the center of the original solid sphere (see figure). The cut-out material and its charge are discarded. What is the magnitude of the electric field produced with this new charge distribution at point P, a distance r = 24.50 m from the center of the original sphere?
