Statement-1: If the distance between the light source and the cathode of the cell is doubled, the stopping potential is doubled.

Answer:

Solution:

Doubling distance reduces point-source intensity to one-quarter

$e V_{s} = h ν - ϕ$

is intensity-independent Stopping potential is unchanged Statement 1 is false, statement 2 true
