Question

what is the magnitude of gravitational force between the earth and a 1kg object on its surface? mass of the earth is 6 into 10 raise to 34 kg and radius of the earth is 6.4 into 10 raise to 6 m

Answer 1

F=m×g
F=1kg×9.8m/s^2
F=9.8N

$\bf Gravitational \: force$ : The force if attraction between two particles towards the centre of the earth, is called gravitational force.

$\bf Universal \: Law \: of \: Gravitation$ : The gravitational force of attraction between any two particles is directly proportional to the product of the masses of the particles and is inversely proportional to the square of the distance between the particles.
