Work done by force of static friction on a system can be zero, can be positive, can be negative, and is always zero. The correct statements are: (1) i and ii, (2) i and iv, (3) only iv, (4) i, ii and iii.
Understand the Problem
The question is asking about the work done by the force of static friction on a system, specifically what can be concluded about its possible values. It presents four statements and asks which combination of them is correct.
Answer
i, ii, and iii
The correct statements are i, ii, and iii.
Answer for screen readers
The correct statements are i, ii, and iii.
More Information
Static friction can do work, such as when it helps move an object like a car on a hill or in a turn, making the work potentially positive or negative depending on the situation.
Tips
Assume static friction is only zero if the object remains at rest relative to the surface.
