Upthrust and Archimedes Principle

The upward force experienced by a body when it is completely or partially immersed in a fluid is called -------

If the upthrust is more than the weight of the body, then body will _______.

The point where weight of the body acts is called ________

The point where buoyant force acts on the body is called ________.

The direction of buoyant force is

• downwards

• sideways

• upwards

• in any direction

The correct formula of upthrust is

• hg

If a body will be put in water, it will weigh

• more than weight in air

• less than weight in air

• same as weight in air

• may be more or less depending on impurities in water

According to Archimedes, loss in weight is equal to

• weight of liquid

• weight of the body

• weight of the liquid displaced by the immersed part of the body

• density of liquid

Upthrust is more in sea water than pure water because

• sea water is salty

• sea water has more density than pure water

• sea water has aquatic animals

• sea water has waves

The weight of 100 ml of water is _______
