Do two objects (two large hunks of lead suspended from two strong strings) exert a gravitational force on each other? If so, why cant we see them attract each other?

Because the gravitational constant G is 6.7 x 10^-7
And it makes the gravitation force relatively small in terms of magnitude.

At least until it doesn't come to the objects with the huge masses (like planets or moons with their 10^20 masses).

Answer:

When two large objects are suspended by long threads then they must attract each other by gravitational force between them

then gravitational force between them is given by the formula

[tex]F = \frac{Gm_1m_2}{r^2}[/tex]

here we know

[tex]m_1 , m_2[/tex] = masses of two bodies

r = distance between them

[tex]G = 6.67 \times 10^{-11} Nm^2/kg^2[/tex]

since gravitational constant is very small between two bodies so the force of gravitation is very small and hence we can not see the two object attracts towards each other
