I assume the stopping potential given in the question is 2 eV

The relation connecting the stopping potential and maximum kinetic energy is given by
 
Kmax = eVo ; Kmax is the maximum kinetic energy, Vo is stopping potential and e is electronic charge.
 
Kmax = 2 eV = 2 × 1.602 × 10-19 Joules = 3.2 × 10-19 Joules
