1.due to solid sphere gravitational field at P E=GM/r^2 E=GM/(1.5a)² E=GM/2.25a² So E=4GM/9a² 2.due to thin spherical shell, the magnitude of gravitational field at 'P' is zero B/C no gravitational force incide the hollow spherical shell( according to sir Issac neuron low) So net gravitational field at point 'P' E= 4GM/9a²
