Which graph might represent a weaker gravitational field than Earth's?

When considering which graph could represent a weaker gravitational field than Earth's, it is essential to understand how gravitational fields are represented in graphs. A gravitational field's strength is often depicted in terms of the force exerted per unit mass. A weaker gravitational field will show a smaller force acting on a mass compared to that of Earth's gravitational field, which is approximately 9.8 N/kg.

For the correct graph, we should recognize that it will have a lower value on the vertical axis, indicating a weaker gravitational force. Thus, if Graph K indicates a gravitational force that is notably less than 9.8 N/kg, it demonstrates a weaker gravitational field.

In contrast, the other graphs might represent values equal to or higher than Earth's gravitational field strength, indicating a stronger or comparable gravitational field rather than a weaker one.

So, if Graph K shows a force less than Earth's gravitational pull, it would effectively represent a weaker gravitational field, making it the appropriate choice.
