Gravitational field intensity at every point inside a hollow spherical shell of uniform density is zero, because gravitational field due to various regions of the spherical shell cancels each other completely as their vector sum is zero.

Q. If gravitational field intensity is $E$ at distance $R /2$ outside from then surface of a thin shell of radius $R$ , the gravitational field intensity at distance $R /2$ from its centre is

Zero
