4. A wristwatch is said to be water resistant up to 10atm. To test this, it is placed on the bottom of a cylindrical tank filled with water and sealed with a piston. What weight should be placed on the piston to test this claim? The tank is 1m deep and has a radius of 0.5m. Also show on a graph the relationship between this weight in function of the radius of the cylinder in order to keep the same pressure at the position of the watch. Answer: W=788kN Variatie van het uitgeoefend gewicht in functie van de straal van de cylinder om constante druk te houden 3500 3000 1m Gewicht [kN] 2500 2000 1500 1000 500 0 0.9 0.7 1 0.1 0.2 0.3 0.8 0.4 0.5 0.6 straal [m]
