Upthrust Doubt
Q1-Why We do not consider mg force while finding the formulae of upthrust?
Due to gravitational force an object partially or fully merge in water and due to upthrust force object experiences upward force then object floats.
->Gravitation force > upthrust force then object sinks
->gravitation force < upthrust force then object floats
this upthrust force is equal to weight of the displaced liquid by floated or merged object in liquid.
