Answer: Option (A) is the correct answer.
Explanation:
Force acting on a dam is as follows.
F = .......... (1)
Now, when we double the depth then it means H is increasing 2 times and then the above relation will be as follows.
F' =
F' = ........... (2)
Now, dividing equation (1) by equation (2) as follows.
=
Cancelling the common terms we get the following.
=
4F = F'
Thus, we can conclude that if doubled the depth of the dam the hydrostatic force will be 4F.
The answer is B. Filtration. it only lets the water through, while the sand will stay on top.
