Homework Statement
A conical flask contains a liquid of density [tex]\rho[/tex] to a height 'h'.
If the area of the base of the flask is A and V is the volume of the liquid in the flask,then the resultant force acting on the curved surface is,
1) h[tex]\rho[/tex]gA - V[tex]\rho[/tex]g horizontally
2) h[tex]\rho[/tex]gA - V[tex]\rho[/tex]g vertically upwards
3) h[tex]\rho[/tex]gA - V[tex]\rho[/tex]g vertically downwards
4) h[tex]\rho[/tex]gA + V[tex]\rho[/tex]g vertically upwards
5) h[tex]\rho[/tex]gA + V[tex]\rho[/tex]g vertically downwards
Homework Equations
Pressure and upthrust
The Attempt at a Solution
since the horizontal components of the forces acting on the curved surface cancel off,(only the downward vertical components add on)so the answer can't be (1) ?
The force acting on the base of the flask is ,
force due to the pressure of the liquid - the weight of the fluid?
h[tex]\rho[/tex]gA - V[tex]\rho[/tex]g downwards, so is this the resultant force acting on the curved surface also?
Thank you
