If \( \vec{b}=3 \hat{i}+4 \hat{j} \) and \( \vec{a}=\hat{i}-\hat{j} \), the vector having the
\( P \)
same magnitude as that of \( \vec{b} \) and parallel to \( \vec{a} \) is
W
(1) \( \frac{5}{\sqrt{2}}(\hat{i}-\hat{j}) \)
(2) \( \frac{5}{\sqrt{2}}(\hat{i}+\hat{j}) \)
(3) \( 5(\hat{i}-\hat{j}) \)
(4) \( 5(\hat{i}+\hat{j}) \)
