The direction of gravitational intensity at point $P$ of a hemispherical shell of uniform mass density is indicated by the arrow ___.

The direction of the gravitational intensity at an arbitrary point P for the hemispherical shell of uniform mass density is directed downward. Due to zero gravitational forces acting on any particles at any point inside a spherical shell, as it is symmetrically placed. Here if we remove the upper hemispherical shell, the net gravitational force acting on a particle at P will be downwards. Hence, gravitational intensity will be along e. The direction of gravitational intensity at point $P$will be along with $e$.
