For a floating body, how is its weight related to the buoyant force?
Complete the following sentence :
Pressure is .................... in all directions about a point in a liquid.
A simple U tube contains mercury to the same level in both of its arms. If water is poured to a height of 13.6 cm in one arm, how much will be the rise in mercury level in the other arm?
Given : density of mercury = 13.6 x 103 kg m-3 and density of water = 103 kg m-3.
Prove that the loss in weight of a body when immersed wholly or partially in a liquid is equal to the buoyant force (or upthrust) and this loss is because of the difference in pressure exerted by liquid on the upper and lower surfaces of the submerged part of body.

- Which of the two will have more volume submerged inside water
- Which of two will experience more upthrust due to water.
