Question:-
A rectangular water tank, full to the brim, has its length, breadth and height in the ratio of 2:12. The ratio of hydrostatic forces at the bottom to that at any large vertical surface is
Option (A)
1/2
Option (B)
1
Option(C)
2
Option(D)
4
Correct Option:
(B)
Question Solution:

Force on the bottom
(FF) = rg(2 x 1)x2 = 4rg
Force on the vertical surface
(F2) = g(2 x 2)x 1 = 4 rg
(F1/F2) = 1
