Respuesta :

The answer is 10 N west

Answer:

D. 10 N west.

Explanation:

Forces along the west and east must be equal to make block static. Let F1 is the force along east, F2 is the force along west. So,

                                   F1=F2

                                   25=15+F

Where, F is the additional force required along west to keep bock in steady state.  

                                    F = 10 N west.

Hence, when 10N additional force is applied along west then block will not accelerate.
