A solid sphere of mas M and radius R is placed in vacuum. The gravitational field at point P at distance r(r > R) from the centre is E. If a concentric spherical section of radius R 2 is removed from the bigger sphere. Then net gravitational field at point P is
(1) E 4                  (2) E 2                   (3) 7 E 8                  (4) E 8
