Question

3. If area increases pressures is reduced for the same force.
4. The buoyant force is more, if the volume of dipping object is less ture or false
​

Answer 1

Explanation:

The weight of the object in the fluid is reduced, because of the force acting on it, which is called upthrust. In simple terms, the principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational constant, g. Thus, among completely submerged objects with equal masses, objects with greater volume have greater buoyancy.

Hence, the statement is true.

Answer 2

Answer:

Answer: We know that Thrust acting on unit area is called Pressure. ... pressure is directly proportional to the applied force. Hence, in simple words we can say that if area will decrease then there will be increase in pressure even if the applied remain constant.
