The unit of Bulk modulus is mcq

MCQ  

The unit of Bulk modulus is .......




Options 

A) N

B) m²

C) N / m²

D) m³

Correct answer : option C ( solution discussed below)



Solution
  • The modulus of rigidity is a ratio of shear stress upon shear strain.

modulus of elasticity (E)
         = stress (pressure)  
             Volumetric strain  

  • stress si unit is N/ m² and shear strain is unit less quanity
So the unit of Bulk modulus of is N / m² (Newton/meter²)
