Question

The dimensions of the ratio of angular momentum to linear momentum is:
Options
A [L]
Correct Answer
B [MLT⁻¹]
C [MLT⁻¹]
D [M'L'T']
Correct Answer

Option A is the correct answer.

Detailed Explanation

Angular momentum L = mvr, dimensions ML²T⁻¹. Linear momentum p = mv, dimensions MLT⁻¹. Ratio L/p = (ML²T⁻¹)/(MLT⁻¹) = L.

Hint

Divide dimensions of angular momentum by linear momentum.
