Sara Eckrich Physics Review Question Unit: Mechanics Year: 1993 Question#: 8 Question: The diagram at the right represents a force acting on point P. Which pair of concurrent forces would produce equilibrium when added to the force acting at point P? (1 ) (2 ) (3 ) (4 ) What is this question really asking? 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? Do you know the behavior of vectors and adding them together? return to top |
