The gravitational attraction between a 20 kg cannonball and a 0.002 kg
marble separated center-to-center by 0.30 m. compute the gravitational
force of the marble.

Explanation:

Given:

Mass of the cannonball (M) = 20 kg

Mass of the marble (m) = 0.002 kg

Distance between the cannonball and marble (d) = 0.30 m

Universal gravitational constant (G) =

Now, we know that, the gravitational force (F) acting between two bodies of masses (m) and (M) separated by a distance (d) is given as:

Plug in the given values and solve for 'F'. This gives,

The same force is experienced by both cannonball and marble.

Therefore, the gravitational  force of the marble is

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
