To solve the question of whether the magnitude and direction of the vector \( \vec{A} - \vec{B} \) are the same as that of \( \vec{B} - \vec{A} \), we can follow these steps: ### Step 1: Understand Vector Subtraction Vector subtraction can be understood as the addition of a negative vector. For example, \( \vec{A} - \vec{B} \) can be rewritten as \( \vec{A} + (-\vec{B}) \). ### Step 2: Analyze the Magnitudes The magnitude of a vector is always a non-negative quantity. When we compute the magnitudes of \( \vec{A} - \vec{B} \) and \( \vec{B} - \vec{A} \): - The magnitude of \( \vec{A} - \vec{B} \) is given by \( |\vec{A} - \vec{B}| \). ...
