As per Einstein's equation, the velocity of emitted electron in photoelectric emission is given by the equation
mv2 = hf - Uw
mv2hf - Uw
mv2 = hf + Uw
mv2hf + Uw
Answer: Option
Explanation:

Some electrons have less energy than Fermi level E and, therefore, more energy than Uw to escape.

Therefore, this equation has inequality sign.
