Question

*How much force is applied to an object when it is completely immersed in the fluid?*

1️⃣ The force equal to the weight of the fluid.
2️⃣ The force equal to the weight of the object.
3️⃣ The force equal to the weight of the fluid displaced by an object.
4️⃣ The force equal to atmospheric pressure.​

Answer 1

Answer:

When an object us immersed in the fluid, the force equal to the weight of the fluid acts upon the object. Thus is also known as upthrust.

Explanation:

• Upthrust is also termed as buoyancy. This force always acts in the upward direction,against the gravity.
• Upthrust depends upon the volume of the object that is submerged and the density of the liquid in which the object is submerged.

Answer 2

Answer: The force applied will be equal to the weight of fluid displaced by an object , submerged either partly or completely.

Explanation: The Principle of Archimedes' states that,

If an object is partially or fully immersed in a fluid at rest, an upward buoyant force also called upthrust is applied on the object whose magnitude is equal to the weight of fluid displaced by an object.

Buoyancy is the tendency of an object to float when submerged in a fluid.

Hence, The correct answer is 3rd.
