point A is 2.50 m from +3.73*10^-8 C charge, and point B is 1.00 m from the charge. ?

what is the potential difference when you go from point A to point B?

    Va = kq/r = k*32.3e-9/2.5m = 134.09

    Vb = kq/r = k*32.3e-9/1m = 335.24

    Va - Vb = Vab = -201.1 Volts

    This makes sense. A positive charge has more potential energy at B 1 meter away from the charge than at A 2.5 meters from the charge.

    The potential is higher at B by

    V = 8.99e9N·m²/C² * 3.73e-8C * [1/1.00m - 1/2.50m] = 201 V

    The route you take from A to B is irrelevant.

    Hope this helps!
