Two particles are thrown simultaneously from points \( A \) and \( B \) with velocities \( u_{1}=2 \mathrm{~ms}^{-1} \) and \( u_{2}=14 \mathrm{~ms}^{-1} \), respectively, as shown
\( \mathrm{P} \) in figure.
The relative velocity of \( B \) as seen from \( A \) in
(1) \( -8 \sqrt{2} \hat{i}+6 \sqrt{2} \hat{j} \)
(2) \( 4 \sqrt{2} \hat{i}+3 \sqrt{3} \hat{j} \)
(3) \( 3 \sqrt{5} \hat{i}+2 \sqrt{3} \hat{j} \)
(4) \( 3 \sqrt{2} \hat{i}+4 \sqrt{3} \hat{j} \)
