Question

u=0,h=44.1,t=3secods find gravitational force​

Answer 1

Answer:

The universal law of gravitation states that every

Concept Insight - Acceleration due to gravity is constant for a heavy object as well as a light object.

Solution 3

According to the universal law of gravitation, gravitational force between two objects of masses M and m at a distance r from each other is given by:

Let mass of Earth be represented by M = 6 × 1024 kg

Let mass of the object be represented by m = 1 kg

Universal gravitational constant, G = 6.7 × 10-11 Nm2 kg-2

Since the object is on the surface of the Earth, r = radius of the Earth (R)

r = R = 6.4 × 106 m
