Fill in physics blanks!! ?

A rightward force is applied to a 10-kg object to move it across a rough surface at constant velocity. The coefficient of friction between the object and the surface is 0.2. Use the diagram to determine the gravitational force, normal force, applied force, frictional force, and net force. (Neglect air resistance.) Fill in the 5 blanks

    Using net (F) = ma we have:

    Force - Friction = ma

    Now, friction = µ.R

    Also, R = mg => 100 Newtons

    Hence, friction = (0.2)10g => 2g

    so, Force - 2g = 0....as acceleration is zero

    Then, Force = 2g => 20 Newtons

    Note: Net force is zero as the pulling force equals the frictional force.

    Solution in image. I used g = 10 m/s/s for nice round numbers.
