Given that the mass of the object is
[tex]m_1=\text{ 1 kg}[/tex]
The mass of the earth is
[tex]m_2=\text{ 6}\times10^{24\text{ }}\operatorname{kg}[/tex]
The radius of the earth is
[tex]d=6.4\times10^6\text{ m}[/tex]
The value of gravitational constant
[tex]G=6.67\times10^{-11}Nkg^{-2}m^2[/tex]
The formula to calculate gravitational force is
[tex]F=\frac{Gm_1m_2}{d^2}[/tex]
Substituting the values, the gravitational force will be
[tex]\begin{gathered} F=\frac{6.67\times10^{-11}\times1\times6\times10^{24}}{(6.4\times10^6)^2} \\ =9.77\text{ N} \end{gathered}[/tex]
The gravitational force is 9.77 N
