    Select Question Language :


    A sonar system measures the depth of a trench by emitting a sound wave and receiving its echo. The time taken to receive the echo is then used in the calculation for finding the depth. If the error in measurement of time is 0.01 seconds and the speed of the sound wave in the sea water is 1500 ± 0.5 m/s, then find the percentage error in the measurement of the depth of the trench.

    Options :-

    1. 0.01%
    2. 0.1%
    3. 1.03%
    4. 0.6%
    5. None of these
