Answer:
[tex]1.0672\times 10^{-9}N[/tex]
Explanation:
[tex]G[/tex] = Gravitational constant = 6.67 x 10⁻¹¹
[tex]F[/tex] = Gravitational force between these spheres
[tex]m_{1}[/tex] = mass of first sphere = 1.60 kg
[tex]m_{2}[/tex] = mass of second sphere = 16 g = 0.016 kg
[tex]r[/tex] = distance between the centers of the sphere = 4 cm = 0.04 m
Gravitational force between these spheres is given as
[tex]F = \frac{Gm_{1}m_{2}}{r^{2}}[/tex]
[tex]F = \frac{(6.67\times 10^{-11})(1.60)(0.016)}{0.04^{2}}[/tex]
[tex]F = 1.0672\times 10^{-9}N[/tex]
