Inertial force is not fictitious (クリ）

A body is pulled with a string to the left on flat plane (without friction). Tension of string is F. That is, the body is accelerated to the left.

At the left end of the body, Newton's third law of motion folds. Action and reaction are equal. Inertial force is not fictitious. But, many explanations start with two bodies. These are invalid.
