Planck’s constant has the dimensions of : A. Energy B. Linear momentum C. Angular momentum D. Force

The correct answer is: A. Energy

Planck’s constant is a physical constant that is the quantum of action. It is the proportionality constant that links the energy of a photon to its frequency. It is also the

Planck’s constant is denoted by the symbol $h$ and has the value $h = 6.62607015 × 10^{-34}$ J s.

The dimensions of energy are $ML^2T^{-2}$. The dimensions of linear momentum are $MLT^{-1}$. The dimensions of angular momentum are $ML^2T^{-1}$. The dimensions of force are $MLT^{-2}$.

Therefore, Planck’s constant has the dimensions of energy.
