What is B the name of dimensional constant whose dimensions are the same as that of angular momentum.

Explanation

To solve the question regarding the dimensional constant whose dimensions are the same as that of angular momentum, we can follow these steps:

### Step 1: Understand the Dimensions of Angular Momentum
Angular momentum (L) is defined as the product of the moment of inertia and angular velocity. Mathematically, it can be expressed as:
\[ L = mvr \]
where:
- \( m \) = mass (M)
- \( v \) = linear velocity (L T\(^{-1}\))
