2a A sphere of radius R=2a is made of a nonconducting material that has a uniform volumetric charge density. The total charge on this sphere is initially 5.0nC. A spherical cavity of radius a is now removed from the sphere as shown in the figure. Here a = 1.7 cm. Find the magnitude of electric field at point P (0,0,y) where y = 17 cm. State your answer in N/C and round it to the nearest unit. Assume the materia does not affect the electric field (no screening or polarizing effects). Take k=8.99×10° Nm² /C²
