\textbf{176-} In the figure, two containers of equal depth are filled with water. If horizontal forces are applied to the surfaces of the containers, $F_1$ and $F_2$ are the forces on the bottoms of containers (1) and (2) respectively, and $P_1$ and $P_2$ are the water pressures at the bottoms. Which relationship is correct? (The masses of the containers are equal.)
\textit{[Figure: Two containers, container (2) with base radius $r$ (wider at top, narrower at bottom) and container (1) with base radius $2r$ (narrower at top, wider at bottom)]}

(1) $P_1 = \dfrac{1}{4}P_2$ and $F_1 = F_2$
(2) $P_1 = P_2$ and $F_1 = 4F_2$
(3) $P_1 = P_2$ and $F_1 = F_2$
(4) $P_1 = 4P_2$ and $F_1 = \dfrac{1}{4}F_2$
