Which model has greater gravitational attraction?

• Model A

• Model B

Answer explanation

The question asks about the model with a higher gravitational attraction. Given the options, the correct answer is Model A. This indicates that Model A must have a larger mass, a shorter distance from the other body, or both, which results in a stronger gravitational force, according to Newton's law of universal gravitation.

This hanging instrument used to measure the weight of objects.

• spring scale

• triple beam balance

If an object has more mass, then it will

• weigh more.
• weigh less.
• weigh the same as an object with less mass.
