Question

In the equation,  the unit of E CANNOT be written as ______

(a) m^2/s^2

(b) J/kg

(c) Pa/m^3

(d) kg.m/s^2

I have been asked this question in an interview for internship.

Query is from Introduction to Fluid Dynamics topic in division Fluid Dynamics of Fluid Mechanics

Answer 1

Correct option is (d) kg.m/s^2

Explanation: From the last term, we can deduce that m^2/s^2 can be the unit of E. From the first term, we get Pa/m^3 and J/kg is equivalent. Kg.m/s^2 is not of the same dimension. Hence, that is the correct choice.
