The force equation for the object is given as: F - μ_kmg = ma where F is the applied force, μ_k is the coefficient of kinetic friction, m is the mass of the object, g is the acceleration due to gravity, and a is the acceleration of the object on the horizontal surface. Solving for μ_k, we get: μ_k = (F - ma)/mg Substituting the given values, we get: μ_k = (11eaa331_f511_550c_9fad_a1b67696a98a_TB6079_11 - (m x 11eaa331_f511_7c1d_9fad_db7782d81e3a_TB6079_11))/mg μ_k = (11eaa331_f511_550c_9fad_a1b67696a98a_TB6079_11/mg) - (11eaa331_f511_7c1d_9fad_db7782d81e3a_TB6079_11/g) Therefore, the correct option is B.
