An electron is accelerated by a potential difference of V volt to acquire kinetic energy equal to maximum kinetic energy of ejected photoelectron from a metal of work function 3.2 eV, using a light of wavelength

2000\,\mathop \mathrm{A}\limits^ \circ \,

Value of V is

View answer and explanation

Correct option: C

3 volt

Option C (3 volt) is correct because the potential difference is equal to the maximum kinetic energy of the ejected photoelectron divided by the electron charge.
