Upthrust and Archimedes Principle

Larger the volume of body submerged in a fluid, ________ will be the upthrust.

• greater

• smaller

A denser liquid will have ______ boyancy than a less dense one.

• less

• more

The upthrust is equal to the

• weight of the floating object

• volume of the floating object

• weight of displaced liquid

• volume of displaced liquid

The force of Buoyancy equals

• volume of body in the liquid

• weight of the submerged part of the body

• weight of the displaced liquid

• (volume of body immersed in liquid) x (density of liquid) x (acceleration due to gravity)

An object having density equal to a fluid will ______,

• float

• sink

• partially submerge

• partially float

The net force on an immersed object when the density of the object is more than the density of the liquid will

• act upwards

• act downwards

• act in both directions

• be zero.

The net force acting on a floating object

• is zero

• always downward

• always upward

• never upward

A nail sinks in water but cork floats.

• density of nail is more than density of water

• density of water is more than density of nail

• density of cork is more than density of water

• density of water is more than density of cork

The volume of liquid displaced by a body equals

• the volume of submerged part of the body

• volume of the body

• weight of the body

• weight of submerged part of the body

The magnitude of upthrust on a body due to a liquid depends on

• volume of submerged part of the body

• density of the liquid

• volume of the liquid

• weight of the body
