    Answer:

    Explanation:

    The work done by the electric field is given by:

    W = qΔV

    Since the positive charge moves from higher potential to lower potential, the work done in moving the proton is:

    V = -q(V₂ – V₁)

    W = -1.6 * 10⁻¹⁹ (-75 – 145)

    W = 3.520*10³ * 10⁻²⁰ J

    W = 3.520*10⁻¹⁷ J
