An enemy plane is at a distance of 300 km from a radar. In how much time will the radar be able to detect the plane? Take velocity of radio waves as $3 \times 10^{8} m / s$

Open in App

Solution

Time taken by the radar to detect the plane $= \frac{2 (s)}{V e l o c i t y} = 2 \times \frac{/ 300000}{/ 3 \times 10^{8}} = 2 \times 10^{5} \times 10^{- 8} = 2 \times 10^{- 3} s e c o n d s = 2 m i l l i s e c o n d s$
