As we have learnt,

 

Relative velocity -

If two bodies are moving at right angle to each other.

- wherein

Relative Velocity of A with respect to B is

V_{AB}=\sqrt{{V_{A}}^{2}+{V_{B}}^{2}}

 

 

V_{AB}=\sqrt{{V_{A}}^{2}+{V_{B}}^{2}} = \sqrt{8^2 + 6^2} = 10m/s


Option 1)

8m/s

Option 2)

12 m/s

Option 3)

10 m/s

Option 4)

14 m/s
