Answer:
the charge the photoelectric effect induce is 0.132 × 10⁻¹¹ C
Explanation:
energy of ultraviolet light =
=
=7.91 × 10⁻¹⁹ J
=4.94 e V
energy released by the electron = 4.94 - 4.70
= 0.24 e V
potential at the surface of sphere =
0.24 =
Q = 0.132 × 10⁻¹¹ C
hence, the charge the photoelectric effect induce is 0.132 × 10⁻¹¹ C
