To find the vector sum of two vectors, you need to use vector addition. The magnitude of the vector sum is equal to the sum of the magnitudes of the individual vectors if they are in the same direction, and the difference of the magnitudes if they are in opposite directions.
In this case, let's consider two vectors A and B with magnitudes 10 units and 15 units, respectively.
To find the possible magnitude of the vector sum, we need to consider both scenarios:
1. If the vectors are in the same direction: The magnitude of the vector sum will be equal to the sum of the magnitudes. So, the possible magnitude of the vector sum will be 10 + 15 = 25 units.
2. If the vectors are in opposite directions: The magnitude of the vector sum will be equal to the difference of the magnitudes. So, the possible magnitude of the vector sum will be 15 - 10 = 5 units.
Therefore, the vector sum of two vectors with magnitudes 10 units and 15 units can never be 5 units, as it is one of the possible magnitudes of the vector sum.
