A cubical body of mass 5kg and side of length 20 cm is half immersed in a liquid .find the magnitude of upthrust on it.taking g=10m/s2
Density of fluid is not given. Upthrust is equal to weight of fluid displaced.
Weight of fluid displaced= Volume of fluid immersed× density of fluid ×g
volume of fluid immersed= volume of liquid displaced. Here density od fluid is not given.
