Final answer:
The new expected force is 1.669 N.
Step-by-step explanation:
According to Newton's law of universal gravitation, the gravitational 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 find the new expected force, we can use the formula: F = G * (m1 * m2) / r^2, where G is the gravitational constant (6.674 × 10^-11 N·m²/kg^2), m1 and m2 are the masses of the objects, and r is the distance between their centers.
For the initial scenario with two objects of mass 25 kg and distance 1 meter, the force is 280 N.
If we change the mass of one object to 100 kg, the new force can be calculated as: F = (6.674 × 10^-11) * (25 * 100) / 1^2 = 1.669 N.
