Question

Q5). The work function of a metal is
5 eV. What is the kinetic energy of
the photoelectron ejected from the
metal surface if the energy of the
incident radiation is 6.2 eV?[1
eV=1.6x10-19 J)
O (A) 6.626x10-19J
O (B) 8.10-10-19
O (C) 1.92x10-18J
O (D) 1.92x10-19)

​

Answer 1

Answer:

=(20ev−5ev)/e

=15eV/e

=15V
