Question

The fundamental dimensional quantities are related by________

(a) Avagadaro’s law

(b) Newton’s second law

(c) Newtons first law

(d) Newton’s third law

The question was posed to me by my college director while I was bunking the class.

I want to ask this question from Dimensional Homogenity topic in chapter Dimensional and Model Analysis of Fluid Mechanics

Answer 1

Correct option is (b) Newton’s second law

Explanation: Newton’s 2^nd law is the most suitable one for determining the dimensional quantities. We know that, F=ma. Where F = Force , m = mass in kg, and a= acceleration in m/s^2.
