An apparatus like the one cavendish used to find g has a large lead ball that is 7.7 kg in mass and a small one that is 0.061 kg. their centers are separated by 0.05 m. find the force of attraction between them. the value of the universal gravitational constant is 6.67259 × 10−11 n · m2 /kg2 . answer in units of n.

The force of attraction between them is

Explanation:

We are going to use the Newton's Gravitational Law to solve this exercise.

The law states that :

The gravitational force between two objects is proportional to their masses and inversely proportional to the square of the distance between their centers.

The equation is :

Where '''' is the universal gravitational constant.

Where '''' and '''' are the masses of the objects.

Where '''' is the distance between the centers of the objects.

If we replace all the data in the equation :

increase masses, decrease separation
