Question

Unit of upthrust is Joule.

• A. True
• B. False

Answer 1

The correct option is B False

1. Upthrust is nothing but buoyant force.
2. When a rigid object is submerged in a fluid (completely or partially), there exits an upward force on the object that is equal to the weight of the fluid that is displaced by the object.

Therefore, Its unit is equal to that of force(since buoyant force is a kind of force), which is N or Newton.
