K.C.S.E Physics Q & A - MODEL 1999PP1QN30

It is observed that when ultraviolet light is shone onto a clean zinc plate connected to the cap of negatively charged leaf electroscope, the leaf collapse. Explain this observation.

ANSWERS

Ultra violet releases electrons from zinc plate by thermal emission.
On removal of electrons, zinc becomes +vely charged.
Positive charge on zinc discharges/ neutralizes the charged on the electroscope.
