the earth is 6x1024 kq, the radius of the earth is 6.4 x 100 m and the
gravitational Constant is 6. 67x10-11 mm²/kg ? Then calculate-
ci) the mutual force of attraction between the body and the earth.

Answer:
Weight of the body,W=63 N
Acceleration due to gravity at height h from the Earths surface is given by the relation:
g
′
=
(1+
R
e
h
)
2
g
Substituting h=R
e
/2,
g
′
=4g/9
Weight of body of mass m at height h is given as:
W
′
=mg
′
=4/9 mg
=4/9×63=28 N
