Final answer:
The force between two objects with masses of 48 kg and 55 kg and a radius of 0.75 m is 8.59 x 10^-8 N.
Step-by-step explanation:
The force between two objects can be calculated using Newton's law of universal gravitation, which states that the force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
To calculate the force, we can use the equation:
F = (G * m1 * m2) / r^2
where F is the force, G is the gravitational constant (6.67 x 10^-11 N*m^2/kg^2), m1 is the mass of the first object, m2 is the mass of the second object, and r is the distance between their centers.
Plugging in the values given, we have:
F = (6.67 x 10^-11 N*m^2/kg^2) * (48 kg) * (55 kg) / (0.75 m)^2
F = 8.59 x 10^-8 N
