Which one of the following physical quantities has the same dimensions as that of Planck’s constant? A. Linear momentum B. Angular momentum C. Force D. Potential energy

Linear momentum
Angular momentum
Force
Potential energy

The correct answer is: A. Linear momentum

Planck’s constant is a fundamental physical constant denoted by h. It is the quantum of action and has the dimensions of energy multiplied by time, or momentum multiplied by length.

Linear momentum is the product of the mass and velocity of an object. It is a vector quantity, meaning it has both magnitude and direction. The SI unit of linear momentum is the kilogram-meter per second (kg m/s).

Angular momentum is the rotational equivalent of linear momentum. It is

the product of the mass of an object, the distance of the object from the axis of rotation, and the object’s angular velocity. The SI unit of angular momentum is the kilogram-meter squared per second (kg m2/s).

Force is an interaction between two objects that causes a change in the motion of one or both of the objects. The SI unit of force is the newton (N).

Potential energy is the energy stored in an object due to its position or state. The SI unit of potential energy is the joule (J).

Therefore, the only option that has the same dimensions as Planck’s constant is linear momentum.
