Question

A wooden object floats in water kept in a beaker. The object is near a side of the beaker. Let P_A, P_B, P_C be the pressures at the three points A, B and C of the bottom as shown in the figure.

P_A = P_B = P_C

Solution

The correct option is A
P_A = P_B = P_C

"If the pressure in a liquid is changed at a particular point, the change is transmitted to the entire liquid without getting diminished in magnitude”

At the same depth inside a liquid, pressure is same. A block floating will not change this affect

Therefore $P_{A} = P_{B} = P_{C}$
