Question

Buoyant force depends on which of the following factors?
(1). Volume of the body
(2). Density of the body
(3). Volume of the liquid
(4). Density of the liquid

(A). 1 and 4
(B). 1 and 3
(C). 1 and 2
(D). 2 and 3

Answer 1

- Hint: We will acknowledge all the factors that the buoyant force depends upon and write them in the solution. Explain them if possible because it will be better. Then see what options are given in the question and match them with our solution.

Complete step-by-step solution -

Buoyant force depends on the following factors-
1-Volume of the body submerged in the liquid or volume of the liquid displaced
2-Density of the liquid
3-Acceleration due to gravity
Volume
When we push a small piece of cork into water, we experience some upthrust on our fingers. Suppose if we push a bigger piece of cork into water, we experience a greater upthrust on our fingers. Thus, it can be said that the buoyancy force increases with increase in the volume of the object.
Density
When we push a small piece of cork into water, we experience some upthrust on our fingers. Let us add some salt to the water and repeat the same experiment. It can be observed that we experience more upthrust on our fingers. With this it can be concluded that buoyancy increases with increase in density.
Acceleration due to gravity
The force of buoyancy also increases with increase in acceleration due to gravity.
Hence, option A is the correct option.

Note: Buoyancy is the force that makes objects float. It is the force applied on an object that is incompletely or completely drenched in a fluid. Buoyancy is brought about by the distinctions in pressure following up on inverse sides of an object drenched in a static fluid. It is otherwise called the buoyant force.
