Yes you just need to add the field due to the two charges; but remember that the E field is a vector!

you're most welcome

Photoelectric current is related to how many electrons are ejected, not to their maximum velocity. When you shine a beam of photons on a metal, it is likely that each photon will hit only one electron. In the process, it will transfer all its energy to the electron. This energy is given by E=hf...
