Q 3110067819.     (i) Find the value of uniform speed of the ant.
Shift the mirror horizontally and coincide it
with the point Q.
Apply the trigonometric formula.
Find the distance of the ant from the mirror.
The object distance is equal to the image
Then find the distance between the ant and its
image, when ant is at P and Q.
Find the difference between the distance of the
ant and the image, when present at P and Q.
Divide the obtained distance by the time taken.
T hen, from this find the rate at which the
distance between the ant and its image changes.
(ii) `0.5 cm s^(-1)`
