    d) - 44

    Explanation:

    given information:

    length, l = 1.2 m

    diameter, d = 0.2 m

    flux, Φ = - 5.0 Nm/C²

    ε₀ = 8.85 x 10⁻¹²

    to find the net charge of the cylinder, we use the following step

    Φ = E/A

    = Q/ε₀

    Q = Φ ε₀

    = (-5.0) (8.85 x 10⁻¹²)

    = - 44.25 x 10⁻¹² C

    = - 44 pC (d)
