The value of gravitational acceleration is:

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.

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

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:
$F equals fraction numerator G M m over denominator R squared end fraction$
$Mass of earth=M= 6 . 0 \times 1 0^{24} k g$
$m=1kg$
$R= 6.4 x 10 6$
$G= 6.67 x 10 -11 Nm 2 /kg$
$Substituting the values we get,$
$F=9.8 N$

The pull exerted by the Earth on a body of mass 1 kg is ___ 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= $fraction numerator G M m over denominator r squared end fraction$

Force of attraction that moon exert on earth= $fraction numerator G M m over denominator r squared end fraction$

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