A particle is moving westward with a velocity \( \overrightarrow{\mathrm{v}}_{1}=5 \mathrm{~m} / \mathrm{s} \). Its velocity changed to \( \overrightarrow{\mathrm{v}}_{2}=5 \mathrm{~m} / \mathrm{s} \)
\( \mathrm{P} \) northward . The change in velocity vector \( \left(\overrightarrow{\Delta \mathrm{V}}=\overrightarrow{\mathrm{v}}_{2}-\overrightarrow{\mathrm{v}}_{1}\right) \) is :

W
(A) \( 5 \sqrt{2} \mathrm{~m} / \mathrm{s} \) towards north east
(B) \( 5 \mathrm{~m} / \mathrm{s} \) towards north west
(C) zero
(D) \( 5 \sqrt{2} \mathrm{~m} / \mathrm{s} \) towards north west
