Stopping Potential — Previous-Year Questions
5 previous-year questions on Stopping Potential, drawn from JEE Mains, JEE Advanced, NEET UG, and CUET papers. Every question carries a worked-out explanation.
Q1. Light of frequency 8 × 10¹⁴ Hz on a metal of φ = 2 eV gives stopping potential of:
JEE 2022Q2. If intensity of light is doubled, V_s:
JEE 2021Q3. Slope of V_s vs f graph is:
JEE 2020Q4. If wavelength of incident light is halved (still above threshold), V_s:
JEE 2019Q5. Stopping potential of a photocell does NOT depend on:
