if tap is closed P=density*g*4m

if tap is open, you have to use Bernouilles equation

Consider the level of tap at ground level.

then the height of the water above this tap level is 4m

so the pressure is given by

P=hdg

therfore, P=4*1000*10

P=40000pa=40KPa

It is necessary to specify because if the tap is open the water starts flowing and to calculate pressure we have to use Bernouli theorm

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
