A fish F, in the pond is at a depth of 0.8m from the water surface and is moving vertically upward with velocity `2ms^(-1)`. At the same instant, a bird B is at a height of 6m from the water surface and is moving downward with velocity `3ms^(-1)`. At this instant. both are on the same vertical line as shown in figure . Which of the following statements are correct?
