1.	How does the stopping potential applied to a photocell change, if the distance between the light source and the cathode of the cell is doubled?
Answer» Stopping potential remains unchanged. Reason: On doubling the distance between the light source and the cathode of the cell, the intensity of light incident on the photocell becomes one-fourth. As stopping potential does not depend on intensity, the stopping potential remains unchanged.
