The correct answer is option 2, Angular momentum.

Planck`s constant, denoted as h, is a fundamental constant in quantum mechanics that relates the energy of a photon with its frequency. It has dimensions of energy times time, which can also be written as Joule-seconds (J·s) or kg·m^2/s.

Angular momentum, denoted as L, is a physical quantity that measures the rotational motion of an object. It has dimensions of mass times velocity times radius, which can also be written as kg·m^2/s.

Comparing the dimensions of Planck`s constant and angular momentum, we can see that they have the same units of kg·m^2/s. Therefore, they have the same dimensions.

It is important to note that the other options listed do not have the same dimensions as Planck`s constant. Linear momentum has dimensions of mass times velocity (kg·m/s), force has dimensions of mass times acceleration (kg·m/s^2), and potential energy has dimensions of energy (J). So, the correct answer is indeed option 2, Angular momentum.
