Which object exerts more gravitational force, object A with a mass of 25 grams and a density of 2 g/cm3 or object B with a mass of 55 grams and a density of 0.5 g/cm3?

Gravitational force depends only upon mass, not density. It is proportional to mass.

yea buddy

To determine which object exerts more gravitational force, we need to use the formula for gravitational force:

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

Where:
F = gravitational force
G = gravitational constant (approximately 6.674 × 10^-11 N m^2/kg^2)
m1, m2 = masses of the objects
r = distance between the centers of the objects

In this case, we only have one object, which means we would compare the gravitational forces between the object and another known mass (for example, Earth), assuming the distance is constant.

Since we're only comparing the two objects A and B, we can ignore the gravitational constant and the distance.

To compare the gravitational forces, we can calculate the weight of each object using the formula:

Weight = mass * gravitational acceleration

Gravitational acceleration on Earth is approximately 9.8 m/s^2.

Now let's calculate the weight of object A:
Weight of A = mass of A * gravitational acceleration

Weight of A = 25 grams * (9.8 m/s^2 / 1000 grams)

Weight of A = 0.245 N

Next, let's calculate the weight of object B:
Weight of B = mass of B * gravitational acceleration

Weight of B = 55 grams * (9.8 m/s^2 / 1000 grams)

Weight of B = 0.539 N

Comparing the weights, we can see that object B exerts more gravitational force than object A.
