Which of the following statement is wrong?

By Ritesh|Updated : October 27th, 2022

(a) If the buoyant force is less than the weight of the object, then the object sinks.

(b) If the buoyant force is greater than the weight of the object, then the object floats.

(c) If the buoyant force is less than the weight of the object, then the object floats.

(d) If the buoyant force is equal to the weight of the object, then the object floats inside the liquid.

The wrong statement is - If the buoyant force is less than the weight of the object, then the object floats. If the buoyant force is less than the object's weight, the object will sink. If the buoyant force equals the object's weight at that depth, the object will stay hung.

Law of Flotation-

(i) When an object is floating in equilibrium, it moves as much fluid as it weighs.

(ii) The removed centre of gravity of the liquid and the centre of gravity of the solid must both lie on the same vertical axis.

Buoyant Force-

  • The property of a fluid that makes objects go higher when it is present. Additionally known as buoyant force.
  • This force acts on the fluid's centre of gravity, which is also known as the centre of buoyancy after the objects have emptied it.

Archimedes' Principle-

  • When an object is fully or partially submerged in a liquid, its weight decreases due to
  • The weight of the fluid that the object has moved is equal to this apparent weight reduction.

Summary:

Which of the following statement is wrong? (a) If the buoyant force is less than the weight of the object, then the object sinks. (b) If the buoyant force is greater than the weight of the object, then the object floats. (c) If the buoyant force is less than the weight of the object, then the object floats. (d) If the buoyant force is equal to the weight of the object, then the object floats inside the liquid.

The claim that something floats if its buoyant force is less than its weight is untrue. The buoyant force is always present in a fluid, regardless of whether an object floats, sinks, or is suspended.
