Answer 1

The force of gravitational is calculated by using the formula:
F= G× m1×m2/r^2
Here, Gravitational constant, G = 6.7×10^-11Nm^2/kg^2
Mass of earth ,m1=6×10^24kg
Mass of ball , m2=1kg
and, distance between center , r= Radius of earth of the earth of ball
= 6.4×10^3km
=6.4×10^3×1000m
=6.4×10^6m
Now, putting these values in the above formula , we get :
F=6.7×10^-11×6×10^24×1/(6.4×10^6)^2
F=9.8N
