hi
electric potential at a point in a electric field is defined as amount of work done in moving a unit positive charge from infinity to that point against electric field ,but my doubt is what actually this infinite distance means here

.Nice question..i got one more with this...when we move a particle from infinite distance to a point where there are no charged particles, we take the work done as zero.. But this is opposing newton's law ?????

In this case, the work done is not mechanical work. It's the electrical work.
So, when there are no charged particles, there are no electric forces. So, on moving a point charge from infinity to any point where there are no other charges, the "Electrical" work done is zero.
So, this doesn't violate the Newton's laws.. 😀
