The dimensional formula of the product of two physical quantities P and Q is `ML^2 T^(-2)`. The dimensional formula of `P//Q` is `ML^0 T^(-2)`. Then what are the units of physical quantities P and Q.

Explanation

To solve the problem, we need to find the units of two physical quantities \( P \) and \( Q \) given their dimensional formulas for their product and their ratio.

### Step 1: Understand the Given Information
We are given:
1. The dimensional formula of the product \( P \times Q \) is \( [P \times Q] = ML^2 T^{-2} \).
2. The dimensional formula of the ratio \( \frac{P}{Q} \) is \( \left[\frac{P}{Q}\right] = ML^0 T^{-2} \).

### Step 2: Set Up the Dimensional Formulas
