A beam of plotons of energy \( 5 \mathrm{eV} \) is incident on a charged metallic sphere of radius \( 1 \mathrm{~m} \) and work function \( 3 \mathrm{e} V \). The sphere is charged to a potential double the stopping potential. Assume that the
\( \mathrm{P} \) electrons are emitted normally with respect to the sphere. What is the maximum distance that the electrons will reach with respect to the center?
W
(A) the electrons will not be emitted at all
(B) \( 2 \mathrm{~m} \)
(C) \( 1.33 \mathrm{~m} \)
(D) \( 4 \mathrm{~m} \).
