------------------------------------------------ Calculate the gravitational force between two 150 kg objects located 25 m apart.

a) 9.8 N
b) 98 N
c) 245 N
d) 490 N

Answer :

Final answer:

The gravitational force between two 150 kg objects located 25 meters apart is calculated using Newton's law of universal gravitation, yielding a value much smaller than the provided options. There seems to be an error in the multiple-choice answers as the gravitational force should be a very small number.

Explanation:

The question involves calculating the gravitational force between two objects using Newton's law of universal gravitation. This law is given by the formula:

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

where:
F is the gravitational force,
G is the gravitational constant (6.674 x 10^-11 N(m^2)/kg^2),
m1 and m2 are the masses of the objects, and
r is the distance between the centers of the two masses.

By plugging the values into the equation, we get:

F = (6.674 x 10^-11) * (150 kg * 150 kg) / (25 m)^2

After performing the calculations, the gravitational force (F) is found to be much smaller than any of the given options (a - d), indicating that there might be an error in the multiple-choice options provided. Nevertheless, in a correctly stated multiple-choice scenario, the correct answer would be the one closest to the calculated value, which typically is a very small number due to the small value of the gravitational constant (G) and the inverse square relation with distance.
