    The acceleration of the object is 4.847m/s^2

    Explanation:

    Acceleration due to gravity g is given by:

    g = (G*M) / R^2

    Where G is gravitational constant

    M is mass of object

    R is radius

    g = (6.6726*10^-11) * (8.4*10^23) / (3.4*10^6) ^2

    g=5.605*10^13/1.156*10^13

    g = 4.847m/s^2
