Question

Choose the INCORRECT dimensions:

• A. Linear momentum: \( MLT^{-1} \)
• B. Angular momentum: \( ML^2T^{-1} \)
• C. Speed of Light: \( M^0 L T^{-2} \)
• D. Kinetic Energy: \( ML^2T^{-2} \)
• E. Angular Frequency: \( M^0L^0T^{-1} \)

Hint:

Remember to verify the physical units for fundamental quantities, like speed or mass, to check their dimensional consistency.

Answer 1

The Correct Option is C

Step 1: The speed of light does not have dimensions of mass or length squared. It is dimensionless with respect to mass and length. 
Step 2: Option (C) incorrectly states the dimensions of the speed of light. 
Step 3: The correct dimensions of the speed of light should be \( L T^{-1} \). 
Hence, (C) is incorrect.
