Introduction to application of upthrust:
If a solid body is immersed partly or wholly in a liquid it experiences an upward force which is called the upthrust force. The formula to find the upthrust force is the product of the volume of the solid inside the liquid, density of the liquid and the acceleration due to gravity. Now we discuss some of the applications of the upthrust force. Having problem with two capacitors in series keep reading my upcoming posts, i will try to help you.
Application of Upthrust:
There are some applications of the upthrust force, which are discussed here.
(i) To find the volume of the body: Let W and w be the weight of the body in the air and in the water respectively. Now according to the upthrust force the loss in the weight in the body is equal to the upthrust force on the body.
W- w = V d g
Where, V is the volume of the body, d be the density of water and g be the acceleration due to gravity.
So, V = (W – w) / dg
By measuring the values of W, w, d and g , find the value of the volume of the body.
(ii) Specific gravity or the relative density of the material of the solid: The specific gravity of a solid with respect to water is given by te ratio of the weight of the body in air to the loss in the weight of the body.
Specific gravity = Relative density = W / (W – w)
Where, W is the weight of the body in air, w be the weight of the body in water.
(iii) Working of a parachute: As a person jumps from the aero plane with the parachute, initially the motion of the person is free fall at that time the parachute is closed. As the parachute opens the volume of the parachute inside the air increases by a very large amount. We know that the upthrust force depends on the volume of body in the fluid, so a large quantity of upthrust is acting on the parachute in the upward direction. Hence, the person reaches on the ground safely. Please express your views of this topic Capacitance Formula by commenting on blog.
Conclusion Fro Upthrust Force:
Due to this upthrust force there is a loss in the weight of the body if it is submerged in the liquid. Upthrust force is due to the pressure difference between the two points in the liquid. The upthrust force exerted by the body due to the liquid is depend on the volume of the body inside the liquid, density of the liquid and the acceleration due to gravity.
