An open cubical tank completely filled with water is kept on a horizontal surface. Its acceleration is then slowly increasesd to `2m//s^(2)` as shown in the figure. The side of the tank is 1m. Find the mass of water that would spill out of the tank.

Text Solution

Verified by Experts

The correct Answer is:
100 kg
`tan theta = (a)/(g) implies tantheta = 0.2`
`0.2=(x)/(1)`
`x=0.2`
mass spill out `=Vrho`
mass spill out `=Axx1xx1000`
mass spill out `=(1)/(2)xx1xx0.2xx1000kg`
mass spill out `=100kg`
