Physics · Friction
Two solid blocks of iron with masses M1 and M2 are lying at rest on a horizontal cemented floor. If M1 is greater than M2, and an attempt is made to slide them, which of the following is correct regarding the limiting static friction experienced by them?
- 1Since both are at rest, their static friction limits are zero.
- 2Both M1 and M2 experience equal limiting force of friction.
- 3M1 experiences a lesser limiting force of friction than M2.
- 4M1 experiences a greater limiting force of friction than M2.✓
Correct answer
M1 experiences a greater limiting force of friction than M2.
