Since p = nhν, calculate n when p = 2 × 10^-3, h = 6.6 × 10^-34, and ν = 6 × 10^14.

1. n = p / hν
2. n = 2 × 10^-3 / (6.6 × 10^-34 × 6 × 10^14)
3. n = 5 × 10^15
4. Thus n = 5 × 10^15.

Correct answer: n = 5 × 10^15

Solution

Using the formula n = p / (hν), substitute the given values: p = 2 × 10^-3, h = 6.6 × 10^-34, and ν = 6 × 10^14. Simplifying, n = (2 × 10^-3) / (6.6 × 10^-34 × 6 × 10^14) = 5 × 10^15.
