Question

In the figure shown, explain the difference between $\overrightarrow{DE}$ and $\overrightarrow{ED}$.

Answer 1

Vectors:

1. The vectors are defined as a quantity containing both magnitude and direction.
2. The length of the segment of the directed line represents the magnitude of a vector.
3. The angle at which the vector is inclined represents the direction of the vector.
4. The starting point of a vector is called “Tail" and the ending point (having an arrow) is called “Head.”

Difference between $\overrightarrow{\mathbf{D}\mathbf{E}}$ and $\overrightarrow{\mathbf{E}\mathbf{D}}$:

1. Now in the given question, we can clearly observe that the $\overrightarrow{DE}$ and $\overrightarrow{ED}$ are equal in magnitude but opposite in direction.
2. DE vector is pointing towards the southwest and ED is pointing towards the northeast.
