Which of the following physical quantities has the same dimensions as that of Planck's constant?
A. Linear momentum
B. Angular momentum✓ Correct Answer
C. Work and energy
D. Surface tension
💡 Solution & Explanation
Planck's constant has dimensional formula ML squared T to the minus one, which matches the dimensions of angular momentum calculated as the product of moment of inertia and angular velocity or linear momentum and radius. Linear momentum shares dimensions with impulse rather than Planck's constant.
