Which physical quantity has the same dimensions as Planck's constant?
A. Linear momentum
B. Angular momentum✓ Correct Answer
C. Force
D. Pressure
💡 Solution & Explanation
Both Planck constant and angular momentum share the identical dimensional formula of squared mass multiplied by length squared per unit time, expressed as [ML^2T^-1]. Linear momentum possesses a dimension of [MLT^-1], whereas force and pressure correspond to dimensions of [MLT^-2] and [ML^-1T^-2] respectively, making them dimensionally distinct.
