Question

An object of uniform density is allowed to float in water kept in a beaker. The object has triangular cross-section as shown in the figure. If the water pressure measured at the three points $A,B$ and $C$ below the object are $P_A,P_B$ and $P_C$ respectively, then:

• A. $P_A>P_B>P_C$
• B. $P_A>P_B<P_C$
• C. $P_A=P_B=P_C$
• D. $P_A=P_B<P_C$

Answer 1

The correct option is C $P_A=P_B=P_C$

As we know, $P=\rho gh$
Hence, at the same vertical height of a static fluid, pressure remains constant (unless fluid is accelerated).
