Answer:
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
