This gravitational force is also known as weight.

In physics, weight is calculated as mass × acceleration due to gravity.

So,

mass × 10m/s² = 669 N

mass = 66.9 kg

Answer:

Mass of an object, m = 68.26 kg

Explanation:

It is given that,

Gravitational force near the Earth's surface, F = 669 N

We have to find the mass of an object which is experiencing this force. It can be determine using Newton's second law of motion as,

F = m a

[tex]m=\dfrac{F}{a}[/tex]

Where, a = acceleration due to gravity

[tex]m=\dfrac{669\ N}{9.8\ m/s^2}[/tex]

m = 68.26 Kg

So, the mass of an object is 68.26kg. Hence, this is the required solution.
