You're asking for the gravitational force between two objects. To calculate this, we need to use Newton's Law of Universal Gravitation:

F = G * (m1 * m2) / r²

Where:

* F is the gravitational force

* G is the gravitational constant (approximately 6.674 × 10⁻¹¹ N⋅m²/kg²)

* m1 and m2 are the masses of the two objects

* r is the distance between the centers of the two objects

Let's plug in the values:

* m1 = 25 kg

* m2 = 55 kg

* r = 4.00 m

F = (6.674 × 10⁻¹¹ N⋅m²/kg²) * (25 kg * 55 kg) / (4.00 m)²

F ≈ 5.77 × 10⁻⁹ N

Therefore, the gravitational force between the two objects is approximately 5.77 × 10⁻⁹ Newtons.
