Question

which phrase describes the effect of gravitational forces on objects? only effects objects with considerable mass or volume no effect on objects that are too small to be seen repulsive under the right conditions always attractive

Explanation:

Gravitational force is a fundamental force of nature. According to Newton's law of universal gravitation, every object with mass attracts every other object with mass. It is always an attractive force, not repulsive. Also, gravitational force acts on all objects regardless of their size (even very small objects, though the effect might be negligible for very small masses). So the phrase "always attractive" correctly describes the effect of gravitational forces. The other options are incorrect: gravitational force acts on all objects with mass (not just those with considerable mass/volume), it acts on small objects too (even if not visible), and it is never repulsive.

Answer:

always attractive
