An object on a rough surface has a maximum static friction of 2 N and kinetic friction of 1 N. If a 5-N push causes the object to slide across the surface, what is the magnitude of the static frictional force while the object is moving

2N

Explanation:

Solution:

- The minimum force of 2N is required to make the box move from static position. When a 5N force is applied that maximum static friction is exceeded by 3 N.

- While the box is moving the static friction is maintained throughout the journey while its moving. Hence, 2N
