ANSWER
F = GMm/d²
F= 6.7 × 10⁻¹¹ N kg⁻²m² × 40kg × 40kg / (2m)²
F = 2680 × 10⁻¹¹ N
F = 2.680 × 10⁻⁸ N

Given:
Mass of object one ( m1) = 40 kg
Mass of object two ( m2) = 40 kg
distance between the two objects (d) = 2m
Universal Gravitational
Constant ( G) = 6.673 × 10^-11 Nm^2kg-2
To find :
Gravitational force of attraction between them=?
Formula :
F = G m1m2
d^2
Solution:
F = 6.673 × 10^-11 × 40 × 40
2^2
F = 6.673 × 40×40 × 10^-11
4
F = 6.673 × 40 ×20 ×10^-11
F = 6.673 × 800 × 10^-11
F = 53.38 ×100×10^-11
F = 53.38×10^-9 N
therefore ,
the Gravitational force of attraction between the two bodies is 53.38×10^-9 N.
