Solution:
Relative velocity is given by \(\vec{v}_{AB} = \vec{v}_A - \vec{v}_B = (3\hat{i}+4\hat{j}) - (7\hat{i}-3\hat{j}) = -4\hat{i}+7\hat{j}\) m/s. Therefore, option D is correct.
Two objects \(A\) & \(B\) are moving in a plane with velocities \(\vec{v}_A = (3\hat{i}+4\hat{j})\) m/s and \(\vec{v}_B = (7\hat{i}-3\hat{j})\) m/s respectively. The velocity of object \(A\) with respect to object \(B\) will be (in m/s):
