    Answer:

    \boxed{\sf Magnification \ (m) = 2}

    Given:

    Object distance (u) = 25.0 cm

    Image distance (v) = -50.0 cm

    To Find:

    Magnification (m)

    Explanation:

    \boxed{\bold{\sf Magnification \: (m) = - \frac{Image \: distance \: (v)}{Object \: distance \: (u)}}}

    Substituting values of Image distance(v) & Object distance (u) in the equation:

    \sf \implies m = - \frac{( - 50)}{25}

    -(-50) = 50:

    \sf \implies m = \frac{50}{25}

    \sf \implies m = \frac{2 \times \cancel{25}}{ \cancel{25}}

    \sf \implies m = 2
