Question

List all the forces acting on the block B in figure.

✓

Answer

As inertial frame is used to understand unknown forces acting on body under motion, as in case of car when breaks are applied no apparent force is applied but still our body moves forward so to understand this frame of reference is used but actually this does not exit.
