Answer 2

To calculate the gravitational force (F) between two objects, we can use Newton's law of universal gravitation:

F = G * (m1 * m2) / R^2

Where: F is the gravitational force between the two objects in Newtons (N). G is the gravitational constant, approximately 6.67 × 10^-11 N m^2/kg^2. m1 is the mass of the first object in kilograms (kg). m2 is the mass of the second object in kilograms (kg). R is the distance between the centers of the two objects in meters (m).

Let's plug in the given values:

m1 = 75T = 75 * 10^3 kg (since 1 tonne (T) = 1000 kg) m2 = 85T = 85 * 10^3 kg G = 6.67 × 10^-11 N m^2/kg^2 R = 30 km = 30,000 m (since 1 km = 1000 m)

Now, we can calculate the force (F):

F = 6.67 × 10^-11 N m^2/kg^2 * (75 * 10^3 kg * 85 * 10^3 kg) / (30,000 m)^2

First, let's multiply the masses:

75 * 10^3 kg * 85 * 10^3 kg = 6,375,000,000 kg^2

Now, let's calculate the denominator:

(30,000 m)^2 = 900,000,000 m^2

Now, let's calculate the force:

F = 6.67 × 10^-11 N m^2/kg^2 * (6,375,000,000 kg^2) / 900,000,000 m^2

F = 4.72 N (approximately)

Therefore, the gravitational force (F) between the two objects is approximately 4.72 Newtons.
