Two identical containers are filled to the same height, one with water and the other with mercury. Which container experiences a greater pressure at the bottom?
The container with water
The container with mercury
Both containers experience the same pressure
Pressure cannot be determined without knowing the container shape

10 N
20 N
40 N
80 N
An object weighs 50 N in air and 40 N when fully submerged in water. What is the volume of the object? (Density of water = 1000 kg/m, g = 10 m/s)
0.001 m
0.005 m
0.01 m
0.1 m
Which of the following factors affects the pressure at a point inside a liquid?
Only depth of the liquid
Only density of the liquid
Both depth and density of the liquid
Neither depth nor density of the liquid
A completely submerged object experiences an upthrust equal to its weight. Which of the following is true?
The object sinks.
The object floats on the surface.
The object remains at equilibrium at any depth.
The object rises to the surface.
A spherical liquid drop of radius 'r' is divided into 'n' identical droplets. If surface tension is 'T', the work done in this process is:
Two soap bubbles of radii and are coalesced isothermally to form a single bubble of radius . If is the external pressure, then the surface tension of the soap solution is:
\frac{P(R^3 - r_1^3 - r_2^3)}{4(r_1^2 + r_2^2 - R^2)}
\frac{P(r_1^3 + r_2^3 - R^3)}{4(R^2 - r_1^2 - r_2^2)}
\frac{P(R^3 - r_1^3 - r_2^3)}{4(R^2 + r_1^2 + r_2^2)}
\frac{P(r_1^3 + r_2^3 + R^3)}{4(r_1^2 + r_2^2 + R^2)}
