The gravitational force of attraction be- tween two students sitting at their desks in
physics class is 3.47 x 10-8 N.
If one student has a mass of 44.8 kg and the other has a mass of 53.9 kg, how far apart are the students sitting? The universal gravitational constant is 6.673 x 10 11 N m² kg?.
Answer in units of m.

please help!! :)

2.15 m

Explanation:

Newton's Law of Universal Gravitation:

List the known values:

Plug these values into the equation:

Notice that the units , , and cancel out. We are left with the unit for radius r.

Get rid of the units to make the problem easier to read.

Multiply the masses together.

Multiply the gravitational constant and the masses together.

Solve for by dividing both sides by 3.47 * 10^(-8) and moving to the left.

Take the square root of both sides.

The students are sitting about 2.15 m apart from each other.

d) the number of neutrons plus the number of protons

b.

hope this : )
