Question

A spherical tank of 1.2m radius is half filled with oil of relative density 0.8

Answer 1

Answer:

The liquid rises along one of the side 

So 

Let rise be h

So

2rh−ga

h=ga×2r              ,since a=10m/s2

                                   h=2r=2.4m

Therefore maximum pressure on the tank = ∫gh

800×10×24=1.92×104Pa

By comparing 2P

P=4800
