In the below figure shows a cube of each side 15 cm immersed in a tub containing water of density `10^3 "kgm"^(-3)` such that its top surface in 20 cm below the free surface of water. Calculate the pressure at the bottom of cube
Take atmosphere pressure = `10^5` Pa and `g=9.8 "ms"^(-2)`

Text Solution

Verified by Experts

Pressure at the bottom surface of cube
`P_2=P_(o) +hrhog`
`=10^(5)+ (0.35xx10^3 xx9.8)`
`=1.0343xx10^(5)` Pa
