The stoping potential is equal to maximum kinetic energy of photo electron in eV

@ vikas 
what excatly your question ?? 
i am not getting it . will u be little bit elaborate the query , so, that we can help u out from this .. 
actually stopping potential is the minimum amount of potential developed in the collector plate so, that it cannot attract the electron that will be emitted by the emitter plate . 
and yes , its equal to the kinetic energy maximu . in the case of law . 
WAITING TO HEAR FROM YOU AGAIN 
ALL THE BEST ..
