MCQ
The pair(s) of physical quantities that have the same dimensions, is (are)
- AReynolds number and coefficient of friction
- BLatent heat and gravitational potential
- CCurie and frequency of a light wave
- ✓All of the above
✓
Answer
Correct option: D.
All of the above
(D) Reynolds number and coefficient of friction are dimensionless.Latent heat and gravitational potential both have dimension $\left[L^2 T^{-2}\right]$.Curie and frequency of a light wave both have dimension $\left[T^{-1}\right]$. But dimensions of Planck's constant is $\left[M L^2 T^{-1}\right]$ and torque is $\left\lfloor M L^2 T\right\rfloor$
