A body is immersed once in each of the following medium? In which case will there be max apperent loss of weight and why?
1) mustard oil. 2) water 3)glycerin
4) petrol
Answers
The answer is glycerin.
Because the density of glycerin is high, compared to that of the other options.
When an object is immersed in a liquid medium, an upward pressure acts on it. This upthrust is called buoyancy. It depends on the density of the liquid and the weight of the object. When the density of the liquid is high, the upthrust is also more and so there is a maximum loss in weight of the object.
option 3) glycerine is the correct answer.
as glycerine has highest density and water has lowest density among the following
when we dip something in higher density medium the medium exerts an upward force on the body hence body losses weight.
formula of weight is
w=mg
when an force(upward) exists in opposite direction to the gravitation the body losses weight.
on the opposite side when we dip something in water it almost contains same weight that body had before dipping in water.
