A block weighing 15N rests on a flat surface and a horizontal force of 3N is exerted on it. Determine the frictional force on the block.
- A. 0.3N
- B. 0.5N
- C. 3.0NCorrect
- D. 5.0N
Explanation
If stationary, static friction exactly balances the applied force: 3.0N. (Note: this question is a near-duplicate of one found in the FUTO 2013/2014 Type D session in this same PDF set; the same independently-worked answer is used here.)
