What is the upthrust experienced by a cube of edge-length 5cm made of iron when completely immersed in ethanol of density 0.8g/cm3. Please answer fast!!!!!
Vol of substance = (5)^3= 125cm^3 density of fluid = 0.8g/cm^3 let acc.due to gravity = 10 m/s^2 upthrust = bouyant force bouyant force =vol.of substance immersed in fluid * density of fluid * acc. due to gravity bouyant force = 125cm^3*0.8g/cm^3*10m/s^2 force=125*8g m/s^2 =1000g m/s^2 =1 kg m/s^2 =1 N
