Let’s check out your problem:

Mice 
A and 
B each went on a quest to find food. Their displacements by the end are represented by vectors 
vec(a) and 
vec(b), respectively.
Which option best describes the meaning of the following statement?

|| vec(a)||=|| vec(b)||
Choose 1 answer:
(A) The mice finished at the same distance from their starting points, but not necessarily in the same direction.
(B) The mice finished at the same distance and in the same direction from their starting points.
(c) The mice walked the exact same path.

Q. Mice A A and B B each went on a quest to find food. Their displacements by the end are represented by vectors a \vec{a} and b \vec{b} , respectively.\newlineWhich option best describes the meaning of the following statement?\newlinea=b \|\vec{a}\|=\|\vec{b}\| \newlineChoose 11 answer:\newline(A) The mice finished at the same distance from their starting points, but not necessarily in the same direction.\newline(B) The mice finished at the same distance and in the same direction from their starting points.\newline(C) The mice walked the exact same path.
  1. Magnitude of a vector: The magnitude of a vector represents the distance from the starting point to the end point, without considering direction.
  2. Equality of magnitudes: The statement a=b|| \vec{a}||=|| \vec{b}|| means that the magnitudes of a\vec{a} and b\vec{b} are equal.
  3. Implication of equal magnitudes: Since only the magnitudes are equal, this implies that the distances traveled by mice AA and BB are the same.
  4. Consideration of direction: However, the statement does not provide any information about the direction of the vectors. Therefore, we cannot conclude that the mice traveled in the same direction.
  5. Correct conclusion: The correct answer is (A) The mice finished at the same distance from their starting points, but not necessarily in the same direction.
