The surface of the inclined plane shown is frictionless. if f = 30 n, what is the
magnitude of the force exerted on the 3.0-kg block by the 2.0-kg block?
3.0 kg
2.0 kg
[18n]

The magnitude of the force exerted on the 3.0-kg block by the 2.0-kg block  is 18 N.

The given parameters;

The net force on the two blocks is calculated by applying Newton's second law of motion as shown below;

Thus, the magnitude of the force exerted on the 3.0-kg block by the 2.0-kg block  is 18 N.

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

i think the answer is a and b

i wish you luck
