From the following which is not correct:
1) work done by external force to bring a unit positive test charge from infinity to a point against electrostatic force is positive.
2) Work done by electrostatic force to bring a unit positive test charge from infinity to a point is positive.
3) At infinity the potential energy is assumed to be zero.
4) The test charge is brought with constant acceleration from infinity to a point against electrostatic force.

Answer:
4) The test charge is brought with constant acceleration from infinity to a point against electrostatic force.
Explanation:
The test charge should be brought with constant velocity. This is attained when the external force applied balances the elctrostatic attractive force.
If the test charge is brought with constant acceleration, the kinetic energy of the test charge gradually increases and makes the problem even more complex.
Humans always tend to find the "minimum" thing, for eg, minimum work done to bring the positive charge from infinity to point P
Hope it helps :)
