Numerical 1: Upthrust on a Cube
A cube of side 0.1 m is submerged fully in water (density = 1000 kg/m³). Find the upthrust on the cube.
Numerical 2: Weight of an Object in Air
An object has a mass of 5 kg. Calculate its weight on Earth (g = 9.8 m/s²).
Numerical 3: Density of an Object
An object has volume 0.02 m³ and mass 30 kg. Calculate its density.
Numerical 4: Object Floating
An object weighs 10 N and displaces 0.001 m³ of water. Find the upthrust and decide if it floats.
Numerical 5: Volume of Displaced Fluid
A cube weighs 20 N in air and 15 N in water. Calculate the volume of water displaced by the cube.
Numerical 6: Upthrust on a Sphere
A sphere of radius 0.05 m is immersed in oil (density = 800 kg/m³). Find the upthrust on it.
Numerical 7: Apparent Weight
An object weighs 50 N in air and 40 N in a liquid. Calculate the upthrust and the density of the liquid (volume of object = 0.002 m³).
