A mercury barometer reads 75 cm in a stationary lift. What reading does it show when the lift is moving downwards, with an acceleration of 1 m/s2? |
|
Answer» Here we have to use Pseudo force connect, acceleration , a = 1 m/s2 is downward so, net acceleration is, an = (g−a) downward. Now formula will be, ρgh′ = ρ(g−a)h Here, h' is final height of barometer, ⇒ h′ = h(1−a/g) Now, put a = 1 m/s2, g = 10 m/s2, h = 75 cm h′ = 75(1 − 1/10) = 75 × 9/10 = 67.5 cm Hence, 67.5 cm is the reading does it show when the lift is moving downward, with acceleration of 1 m/s2. |
