A block weighing 15N rests on a flat surface and a horizontal force of 3N is exerted on it. Determine the friction force on the block
- 0.3N
- 0.5N
-
3.0N
- 5.0N
The correct answer is: C
Explanation
Given that:
Weight of the block: 15N
Horizontal force applied: 3N
Since the applied force (3 N) is less than the maximum static friction (which can be greater than or equal to the weight of the block), the friction force will match the applied force to prevent motion
Therefore, The friction force on the block is: 3N
