Problem

A photocell gives a saturation current of

8\,\mu\text{A}

when illuminated by monochromatic light of intensity

4\,\text{W m}^{-2}

(frequency >

\nu_{0}

). Keeping all other factors unchanged, what will be the saturation current if the intensity is increased to

10\,\text{W m}^{-2}

? a)

12\,\mu\text{A}

3.2\,\mu\text{A}

20\,\mu\text{A}

32\,\mu\text{A}
