Given Information:
We are given three vectors, vector A, vector B, and vector C, such that vector A + vector B + vector C = 0. It is also mentioned that two of the vectors have equal magnitudes, and the magnitude of the third vector is √2 times that of the two vectors with equal magnitudes.
To Find:
We need to determine the angle between the vectors.
Solution:
Step 1: Analyzing the Given Information
Let's denote the magnitude of the vectors with equal magnitudes as 'x'. Since the magnitude of the third vector is √2 times that of the vectors with equal magnitudes, its magnitude will be √2x.
Step 2: Vector Addition
Given that vector A + vector B + vector C = 0, we can rewrite it as:
vector A + vector B = -vector C
Step 3: Magnitude of Vector C
The magnitude of a vector is given by the formula:
| vector | = √(vector x² + vector y² + vector z²)
Since vector C = -(vector A + vector B), we can substitute this in the magnitude formula:
| vector C | = √((vector A + vector B) x² + (vector A + vector B) y² + (vector A + vector B) z²)
Step 4: Expanding and Simplifying
Expanding the above equation, we get:
| vector C | = √(vector A x² + 2(vector A)(vector B) + vector B x² + vector A y² + 2(vector A)(vector B) + vector B y² + vector A z² + 2(vector A)(vector B) + vector B z²)
Since vector A and vector B have equal magnitudes 'x', this equation simplifies to:
| vector C | = √(2x² + 2x² + 2x²) = √(6x²)
Similarly, we can find the magnitude of vector C using the given information:
| vector C | = √(√2x²) = √2x
Step 5: Equating and Solving for x
Since the magnitude of vector C can be calculated in two different ways, we can equate the two expressions:
√(6x²) = √2x
Squaring both sides of the equation, we get:
6x² = 2x²
Simplifying, we find:
4x² = 0
Since the magnitude of a vector cannot be zero, this equation has no solution.
Step 6: Conclusion
The equation has no solution, which means it is not possible to have two vectors with equal magnitudes and a third vector with a magnitude √2 times that of the other two vectors while satisfying the condition vector A + vector B + vector C = 0.
Therefore, the given scenario is not possible, and we cannot determine the angle between the vectors.
