The minimum energy required to remove the electron from metal surface is `7.50 xx 10^(-19) J`. What will be the stopping potential required when this metal surface is exposed to U.V. light of `lambda = 375 Å` ?

Explanation

To solve the problem, we need to calculate the stopping potential required when a metal surface is exposed to UV light of a given wavelength, using the principles of the photoelectric effect.

### Step-by-step Solution:

**Step 1: Understand the Given Data**
- The minimum energy required to remove an electron from the metal surface (work function, W) is given as:
\[
W = 7.50 \times 10^{-19} \text{ J}
