An electron is pushed into an electric field where it acquires a 1-v electric potential. if two electrons are pushed the same distance into the same electric field, the electric potential of both electrons is

Given here that through the same region 2 electrons are pushed by same distance

As we know that electric potential can be relate with electric field by following relation

Since the two electrons are pushed through same electric field by same distance

So the product of E and d will be same

So the electric potential will be same as initial

so V = 1 volt for two electrons

the answer is a. hope this .
