Applying Bernoullie's theorem,

ΔP=ρ_airgh

or, ΔP=(760-735)mm of mercury=25mm of mercury=(25mm)*(density of mercury)*g=(25*10^-3)*(13.6*10³)g

where, ρ_mercury=13.6*10³kg/m³

25mm=25*10^-3m

Hence height of mountain

h=25*13.6/1.2=283.34m

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.
