196 N
200 N
210 N
250 N
Understanding the Answer
Let's break down why this is correct
The maximum static friction force is found by multiplying the coefficient (0.4) by the normal force. Other options are incorrect because Choosing 200 N suggests using a rounded weight of 500 N instead of the exact 490 N; Selecting 210 N likely adds 10 N to the correct result, maybe thinking friction equals 0.42 instead of 0.4.

Definition
Friction in Physics refers to the force that opposes motion between two surfaces in contact. It plays a crucial role in determining how objects move on surfaces and is influenced by the normal force and the friction coefficient. Understanding friction is essential for analyzing the behavior of objects on horizontal and inclined surfaces.
