Calculate the force of gravitation due to earth on a man of mass 100 kg standing on the ground.

Why does the earth not seem to move towards an apple falling towards it?

The correct option is c)The acceleration gained by the earth is not sufficient for its motion to be apparent.
Acceleration is inversely proportional to mass, so gravitational acceleration can be ignored.
The apple falls to the earth, but the earth does not move towards the apple because acceleration is inversely proportional to mass. The Earth's mass is very large compared to the apple, so the acceleration towards the apple is negligible.

The pull exerted by the Earth on a body of mass 1 kg is ___ N.

The correct option is c)9.8.
From Newton's law of universal gravitation, we know that the gravitational force between objects is given by the following formula:

Mass of earth=M= 6.0×10²⁴kg
$m=1kg$
R= 6.4 x 10⁶
G= 6.67 x 10^-11 Nm² /kg
$Substituting\; the\; values\; we\; get,$
$F=9.8\; N$
 
 

Gravitational force attracts the earth and the moon to each other. The earth attracts the moon with the following force:

The correct option is b)Same as that exerted by the moon.
Let m and M be the masses of the moon and the earth separated by a distance r.

Force of attraction that earth exert on moon=

Force of attraction that moon exert on earth=

This shows that they both exert same pressure on each other.
