As can be seen from the figure, ball A floats and ball B floats, so the buoyancy of both balls is equal to their own gravity, while the two balls are the same and the gravity is equal, so FA = FB = g. 。

Because ball a floats, ρ A > ρ ball,

Because B ball is suspended, ρ B = ρ ball,

Then the density relationship between the two liquids is: ρ a > ρ b;

Because the liquid levels of the two containers are equal, according to the formula p=ρgh, the relationship between the pressure on the liquid at the bottom of the container can be obtained as follows: P A > P B.

So the answer is: equal to; be more/bigger than
