In the following figure, four beakers of different base areas contain water as shown

The pressure at the bottom is maximum for the beaker

A beaker contains mercury to a depth of 4 cm and above it there is water of depth 12 cm. What is the total pressure acting on the bottom of the beaker? [density of mercury = 13.6g*cm^(-3) , atmospheric pressure = 76 cm of mercury]

The white of an egg, common salt, sugar and fine sand are added to water separately in beakers as shown below. The mixture is stirred well. A suspension will be formed in the beaker

Four identical beakers contain same amount of water as shown below. Beaker 'a' contains only water. A lead ball is held submerged in the beaker 'b' by string from above. A same sized plastic ball, say a table tennis (TT) ball, is held submerged in beaker 'c' by a string attached to a stand from outside. Beaker 'd' contains same sized TT ball which is held submerged from a string attached to the bottom of the beaker. These beakers (without stand) are placed on weighing pans and register reading W_(a), W_(b), W_(c) and W_(d) for a, b, c and d, respectively. (Effects of the mass and volume of the stand and string are to be neglected)

A coin placed at the bottom of a beaker appears to be raised by 4.0 cm. If the refractive index of water is 4/3, find the depth of the water in the beaker.
