Question

which of the following quantities cannot be exoressed in volts?
potensial
potensial difference
emf
work done​

Answer 1

Stress has the units of Force/Area = N/m

2

, while strain (=Δl/l) is dimensionless. So option A is correct.

Surface tension is Force/Length, thus N/m, hence B is also correct.

Energy has the units of [ML

2

T

−2

], hence the units have to be kgm

2

/s

2

. Thus C is incorrect option.

Pressure is Force/Area = N/m

2

, thus D is again correct.
