Multiple choice

Two surfaces A and B have a static friction of 100 N. Which of the following can be the sliding friction between A and B?

  1. 110 N

  2. 90 N

  3. 115 N

  4. 150 N

  5. 145 N

B Correct answer
Explanation

This is the correct option. As sliding friction is always lesser than the static friction, then if the static friction between two bodies is 100 N, then the sliding friction between them will be 90 N.
