Question

Which of the following is NOT the unit of upthrust?

• A. kgf
• B. N
• C. kg m/$s^2$
• D. Pa

Answer 1

The correct option is D Pa

When a body is partially or wholly immersed in a fluid, an upwards force acts on it. This upwards force is known as upthrust.
The SI unit of upthrust is:
newton (N) = kgf = kg m/$s^2$

Pa (pascal) represents the unit of pressure.
