Question

Calculate the force between two objects that have

Answer 1

$\text { The force between the given two objects is } 1.865 \times 10^{-6} \mathrm{N}$

Explanation:

As per given question,

$m_{1} \text { is } 140 \mathrm{kg}$

$m_{2} \text { is } 160 \mathrm{kg}$

R is 0.895 m

The force between two objects is  

$\mathrm{F}=\frac{G m_{1} m_{2}}{R^{2}}$

Where,

F is the force of attraction between two objects in Newton’s (N)

$\text { G is the Universal Gravitational Constant }=6.674 \times 10^{-11} \mathrm{N}-\mathrm{m}^{2} / \mathrm{kg}^{2}$

$m_{1} \text { and } m_{2} \text { are the masses of the two objects in kilograms (kg) }$

R is the separation in meters (m) between the objects

Substitute the given values in the above formula,

$F=\frac{6.674 \times 10^{-11} \times 140 \times 160}{0.895^{2}}$

$F=\frac{1.494 \times 10^{-6}}{0.801}$

$\mathrm{F}=1.865 \times 10^{-6}$

$\text { The force between the given two objects is } 1.865 \times 10^{-6} \mathrm{N}$
