Answer:
If the friction force on an object is -210 N and the net force acting on the object is 190 N, then we can use the formula:
Net force = Applied force - Friction force
Solving for the applied force, we get:
Applied force = Net force + Friction force
Substituting the given values, we get:
Applied force = 190 N + (-210 N)
Applied force = -20 N
Therefore, the applied force on the object is -20 N. This means that the direction of the applied force is opposite to the direction of motion of the object.
