Sample Questions

1multiple correct

Which factors affect the magnitude of upthrust on a body?

Show answer

Volume of body submerged in fluid, Density of the fluid

Upthrust depends on two main factors: the volume of the body submerged in the fluid and the density of the fluid. Color, shape, and temperature don't directly affect upthrust.

2multiple choice

Relative density has:

Show answer

No unit

Relative density is a ratio of two densities, so it has no unit. It's the ratio of density of substance to density of water at 4°C.

3multiple choice

A cork floats on water because:

Show answer

Its density is less than water

Cork floats because its density (0.24 g/cm³) is less than water's density (1 g/cm³). This means upthrust exceeds its weight when partially submerged.

4multiple choice

When a body is completely immersed in water, the upthrust is:

Show answer

Maximum

When a body is completely immersed, maximum volume of fluid is displaced, giving maximum upthrust. Partial immersion gives less upthrust.
