What is the

Answer :

Firstly, we will calculate the magnitude of gravitational force by using the formula:

F = G× (i)


We know that,


Gravitational constant, G = 6.7 × 10-11 Nm2/kg2


Given,


Mass of earth, m1 = 6.4 × 1024 kg


Mass of object, m2 = 1kg


Distance between centre of earth and object=Radius of earth, r = 6.4× 106 m


Putting all the values in (i), we get:


F = = 9.8144 N


Therefore, the magnitude of gravitational force is 9.8144 N
