Consider the following statements:

(1) Volt is the unit of electrostatic potential

(2) The work done to move a unit positive charge from infinity to a point is the electrostatic potential.

(3) The work done to move a unit positive charge from one point to another point is an electrostatic potential difference

(4) Electrostatic potential is given by \(V = \frac{q}{W}\)

Which of the following is/are true about an electrostatic potential?
