In the parallelogram method of vector addition, two vectors are drawn from the same point as adjacent sides of a parallelogram. What does the diagonal passing through the common point represent?
The resultant vector in both magnitude and direction
The question is related to the concept of vector addition using the parallelogram method in physics or engineering mechanics. Let's understand the resolution:
Concept of Parallelogram Rule of Vector Addition:
- The parallelogram method involves placing two vectors such that they originate from the same point.
- These vectors are treated as adjacent sides of a parallelogram.
- The diagonal of the parallelogram that passes through the point where the vectors originate represents the resultant vector.
Explanation:
- Definition of the Resultant Vector: The resultant vector is the vector that represents the combined effect of the two vectors. It has both magnitude and direction which reflect the net effect of combining the original vectors.
- Visual Representation: When two vectors A and B are positioned as adjacent sides from a common initial point, the diagonal through this common point displays the resultant vector in both magnitude and direction.
- Verification against Options:
- The average of the two vectors: Incorrect because the diagonal doesn't represent the arithmetic average in vector magnitude.
- The resultant vector in both magnitude and direction: Correct as explained above.
- The scalar sum of the two vectors: Incorrect because vectors are added vectorially, not scalarly.
- The difference between the two vectors: Incorrect since the diagonal provides the sum result, not the difference.
Conclusion: Based on the above explanation, the diagonal of the parallelogram passing through the common point represents the resultant vector in both magnitude and direction.
