Question

which one of the following quantities is not expressed in proper units
A) Surface tension J/m square
B) Rigidity modulus N/ m square
C) Coefficient of viscosity NS m/s2
D) Potential energy kg m/s2​

Answer 1

Answer:

coefficient of viscosity NS m/s2

Answer 2

Answer:

option D is wrong unit

Explanation:

the unit (a), (b) and (c) are correct

The unit of potential energy= mgh

hence the or unit= kg.m/s^2*m= kgm^2s^-2

OR

dimension of potential energy= [ML^2T^-1]

therefore, option D kgm/s^-2 is wrong answer
