Comprehension (Q. 7 to 8): In a Photoelectric effect setup, a point source of light of power \(3.2 \times 10^{-3} \mathrm{~W}\) emits mono energetic photons of energy \(5.0 \mathrm{eV}\). The source is located at a distance of \(0.8 \mathrm{~m}\) from the centre of a stationary metallic sphere of work function \(3.0 \mathrm{eV} \&\) of radius \(8.0 \times 10^{-3} \mathrm{~m}\). The efficiency of photo electrons emission is one for every \(10^6\) incident photons. Assume that the sphere is isolated and initially neutral, and that photo electrons are instantly swept away after emission. 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
