0.667 μN
The gravitational force between two objects can be calculated using the formula:
F = G * (m1 * m2) / r^2
where F is the force, G is the gravitational constant (approximately 6.67 x 10^-11 N*(m^2)/(kg^2)), m1 and m2 are the masses of the two objects, and r is the distance between their centers.
In this case, we have m1 = 200 kg, m2 = 200 kg, and r = 2 meters. Plugging these values into the formula gives:
F = 6.67 x 10^-11 N*(m^2)/(kg^2) * (200 kg) * (200 kg) / (2 m)^2
F = 6.67 x 10^-11 N*(m^2)/(kg^2) * 40000 kg^2 / 4 m^2
F = 6.67 x 10^-11 * 10000 N
F = 0.667 * 10^-6 N
So the gravitational force between the two objects is approximately 0.667 micronewtons (0.667 * 10^-6 N).
