Two cars A and B are moving with velocities 8i + 6j and 12i + 5j respectively with respect to the ground. What will be the magnitude of the relative velocity of first car with respect to second car?

The velocity of object B in the rest frame of another object A is known as relative velocity.
relative velocity = velocity of A wrt ground - velocity of B wrt ground
Given in the question :
Va =8i +6j
Vb =12i +5j
in the questionit is given that we have to find relative of A wrt to B
= Vb-Va
=(12i +5j) -(8i +6j)
= 4i-j
Hence, the relative velocity is 4i-j .
