The figure shows four liquids that have equal masses kept in identical containers. The correct answer with ascending order of densities is
K > L > M > N
N > L > M > K
N > M > K > L
N > K > M > L
The figure shows four identical hydrometers floating on four different liquids. Then the liquid with the highest density is,
T
U
V

Pressure is a
Vector
Scaler
Hydrostatic pressure is caused by
The weight of the liquid above
Atmospheric pressure
Inter molecular forces
The motion of fluid particles.
"Pressure is always acting in the direction of the force that causes the pressure." This statement is
Correct
Wrong
Hydrostatic pressure has no direction.
Correct
Wrong
The pressure at a certain point in a liquid depends on the height of the liquid column above that point.
Correct
Wrong
The pressure at the same level of a liquid is the same.
Correct
Wrong
Liquid pressure depends on the vertical height of the liquid column. It does not depend on the shape of the liquid column.
Correct
Wrong
Archimedes principle says that.
When an object is submerged in a fluid, the up-thrust acting on it is equal to the weight of the object.
When an object is completely submerged in a fluid, the up-thrust acting on it is equal to the weight of the object.
When an object is partially or completely submerged in a liquid, the up-thrust acting on it is equal to the weight of the liquid displaced by the object.
When an object is partially or completely submerged in a fluid, the up-thrust acting on it is equal to the weight of the fluid displaced by the object.
When an object of volume V is fully immersed in a liquid of density d, the up-thrust on it is equal to,
vd
vdg
gvd
vdg
dvg
For an object to float on water
Up-thrust is equal to the weight only if it is fully submerged.
Up-thrust is less than weight when it is partially submerged.
Weight is equal to the up-thrust on it
