Explanation

To solve the problem, we will match the statements in Column-I with their corresponding results in Column-II step by step.

### Step 1: Analyzing Statement P
**Statement P:** If photons of ultraviolet light of energy 12 eV are incident on a metal surface with a work function of 4 eV, then the stopping potential (in eV) will be.

- **Given:**
- Energy of photons (E) = 12 eV
- Work function (φ) = 4 eV
