Q11

Thee horizontal component of buoyant force is

A.
negligible
B.
same as buoyant force
C.
zero
Answer
D.
none of the above

Answer: Option C

Solution

Answer: Option C
Solution:
Buoyant force is the upward force exerted by a fluid on a submerged or partially submerged object.

This force acts vertically upward through the center of buoyancy, which is the centroid of the displaced fluid volume.

Since pressure in a fluid acts equally in all directions at a given depth, any horizontal forces acting on opposite sides of the object cancel each other out.

As a result, the horizontal components of the pressure forces balance out, and only the vertical component remains as the net buoyant force.

Conclusion: The horizontal component of buoyant force is zero, making Option C the correct answer.
