Dual Nature of Radiation and Matter question

2001 · Q141

NEETPhysicsDual Nature of Radiation and MatterMCQ+4 / −1
A photo-cell is illuminated by a source of light, which is placed at a distance d from the cell. If the distance become d/2, then number of electrons emitted per second, will be
  1. A
    remain same
  2. B
    four times
  3. C
    two times
  4. D
    one-fourth
View written solutionFree

Correct answer: B

As Intensity becomes 4 times. So number of electrons emitted per second also becomes 4 times.
