Question

6 multiple choice 1 point how does the size of an object’s gravitational field compare to earth’s? the size of the field never changes smaller objects have smaller gravitational fields it is the same size as earth’s field larger objects have smaller gravitational fields

Explanation:

To determine the correct answer, we analyze the concept of gravitational fields. The strength (and size, in terms of influence) of a gravitational field depends on the mass of the object. According to the law of universal gravitation, the gravitational field (or the gravitational force exerted) by an object is proportional to its mass. Smaller objects (with less mass) will have smaller gravitational fields compared to larger, more massive objects like Earth.

• "The size of the field never changes" is incorrect because gravitational fields depend on mass (and distance), so they can change.
• "It is the same size as Earth’s field" is incorrect because most objects have different masses than Earth, so their gravitational fields will differ.
• "Larger objects have smaller gravitational fields" is incorrect; larger (more massive) objects should have larger gravitational fields, not smaller.
• "Smaller objects have smaller gravitational fields" is correct because a smaller mass leads to a smaller gravitational field.

Answer:

B. Smaller objects have smaller gravitational fields (assuming the options are labeled as A, B, C, D with A being "The size of the field never changes", B being "Smaller objects have smaller gravitational fields", C being "It is the same size as Earth’s field", D being "Larger objects have smaller gravitational fields")
