Question

Spring balance can be used to measure the frictional force?

• A. True
• B. False

Answer 1

The correct option is A True

To measure the frictional force offered by a surface on an object tie the object kept on the surface to the spring balance and pull the spring balance parallel to the surface so as to make the object slide on it.
Note the change in spring's scale just before the object starts to slide on the surface. The reading of the spring balance gives the frictional force.
