Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. Linear momentum
  2. Angular momentum
  3. Energy
  4. Force

Correct answer and explanation

Correct answer: Angular momentum

Explanation: āœ… Correct Answer: B) Angular momentum šŸ“š Explanation: Planck's constant (h¯) has the dimensional formula of [ML2T-1]. This is exactly identical to the dimensional formula of angular momentum. Both quantities represent the product of energy and time, or distance and linear momentum.
