Explanation by: John D (no last names) [ Return to question menu
]Answer 1
Incorrect Answer 1 is incorrect because the force of the vector is southeast, not equal and opposite to the vector in the question. return to top
Answer 2
Incorrect Answer 3 is incorrect because the force of the vector is directed northeast, the same as the vector in the question, which if added would not create equilibrium. return to top
Answer 3
Incorrect Answer 3 is incorrect because the force of the vector is pointed to the northwest, which is not equal and opposite to the vector in the question return to top
Answer 4
Correct Answer 4 is correct because the force of the vector is directed southwest, which is equal and opposite to the vector in the graph, which if added would create an equilibrium. return to top
What's this question really asking?
