Dear student,

Q.5 The magnitude of the gravitational force between earth and an object is given by the formula.
$F=\frac{GMm}{r^2}$
where G is the universal gravitational constant G=6.7 x 10^–11 Nm² kg^–2
mass of earth M= 6 x10²⁴ kg
mass of object m= 1kg
r =radius of earth =6.4 x10⁶ m.
$F=\frac{6.7\times {10}^{-11}\times 6\times {10}^{24}\times 1}{{(6.4\times 10}^{}}$⁶)2
$F=9.8N$
hence the magnitude of the gravitational force between earth and 1 kg object on its surface is 9.8N

Q.6. According to the universal law of gravitation and Newton's third law, we know that the force of attraction between two objects is the same but in the opposite direction. Thus the earth attracts the moon with the same force as the moon exerts on earth but in opposite directions.
And if you use gravitational law to calculate the force;
with the mass of earth = 6 x10²⁴ kg
mass of moon= 7.3 x 10²² Kg
distance between them= 384,400,000 m
And G=6.7 x 10^–11 Nm² kg^–2
The gravitational force exerted by the earth on the moon is 2.01 x 10²⁰ N. and this same force is acting by the moon on earth only in opposite direction.
