Question

A fish, F in the pond, is at a depth of 0.8 m from water surface and is moving vertically upwards with velocity 2 m s to the power of negative 1 end exponent At the same instant, a bird B is a height of 6m from water surface and is moving downwards with velocity 3 m s to the power of negative 1 end exponent At this instant both are on the same vertical lines as shown in the Figure. Which of the following statement(s) is(are) correct?
i) Height of B, observed by F (from itself) is equal to 5.30 m.
ii) Depth of F, observed by B (from itself) is equal to 6.60 m.
iii) Velocity of B, observed by F (relative to itself) is equal to 5.50 m s to the power of negative 1 end exponent
iv) Velocity of F, observed by B (relative to itself) is equal to 4.50 m s to the power of negative 1 end exponent

  1. (i) & (iii) are correct    
  2. (ii) & (iv) are correct    
  3. all are correct
