Question

by how much force does earth attracts a body of mass 1 kilogram​

Answer 1

The earth attracts a body of mass 1kg with a force of 10N.

Answer 2

Given:

Mass of 1 kg.

To find:

Magnitude of gravitational force?

Calculation:

Gravitational force on body of 1 kg will be :

$\rm F = \dfrac{GMm}{ {d}^{2} }$

• M is mass of earth , m is mass of object and d is radius of earth.

$\rm \implies F =m \times \dfrac{GM}{ {d}^{2} }$

• GM/d² is written as 'g' or gravity and equal to 9.8 m/s².

$\rm \implies F =m \times g$

$\rm \implies F =1 \times 9.8$

$\rm \implies F =9.8 \: N$

So, gravitational force on mass is 9.8 N.
