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
Answer:

A pendulum's time period is the amount of time it takes to complete one oscillation. The pendulum with a length of 3.98 m and a length of 99.4 cm will have a time period of 4 and 1.99 seconds, respectively.
<h3>What is the definition of a simple pendulum?</h3>A simple pendulum is a device with a point mass hanging from fixed support and connected to a light inextensible thread.
The vertical line going through the fixed support represents the mean position of a basic pendulum.
h = vertical distance from the point of suspension
L = length of the simple pendulum
The time period of the simple penduum is given by
For l = 3.98 m
T = 4 second
For l = 99.4 cm = 0.994 m
T = 1.99 second
The time period of the pendulum having 3.98 m and 99.4 cm in length will be 4 and 1.99 seconds respectively.
