It has been explained that for an electron to be ejected out, a photon with energy equal to the work function or more, has to collide with the electron. If the photon has extra energy, then this is used up as kinetic energy for the electron. But what is a photon has exactly the same energy as work function? does this mean the electron will not have any kinetic energy?

Answer:
Yes. This means that the electrons will be just knocked out of the surface but it will have zero kinetic energy.
