A plastic sphere of radius 16 cm is uniformly charged. The electric field intensity at its surface is 6 ´ 104 N/C. The electric field at a distance of 8 cm from its centre isin 104 N/C

Electric field inside a nonconducting charged sphere is proportional to distance from the center inside the sphere.Here radius is 16 cm and other point is 8 cm from the center.E1E2=Rr= 168=2E2=E12=3×104
