Question

Water is filled in a flask upto a height of 20cm. The bottom of the flask is circular with radius 10cm. If the atmospheric pressure is 1.013×105 Pa, find the force exerted by the water on the bottom . Take g=10ms-2 and density of water =1000kgm-3.

Now , here if I draw the FBD of the base of flask. Then , there are 3 pressures acting on the block . Atmospheric pressure acting from top and below because fluids exerts pressure in all directions. Then is the hpg pressure. Total pressure on the bottom of flask is . P0 -P0 + hpg. Is this correct?

Answer 1

Answer:

if the flsk is upto a height of 20 cm then the g will be 1000kg
