In MKS system, the unit of pressure is:
Correct answer: C. Pascal
- A. Dyne
- B. Atmosphere
- C. Pascal
- D. cm of Hg
Explanation
The Pascal (Pa) is the correct unit of pressure in the MKS system. It is defined as one Newton per square meter. Mathematically, pressure (P) is given by the formula: P=F/A, where F is force and A is area. In terms of units, 1 Pascal is equal to 1 Newton per square meter.
