in an experiment to study the relation between force of limiting friction and normal reaction a body starts sliding on applying 439 so what will be the magnitude of force of friction acting on body when applied force on it are 0.5 Newton 1 Newton 2.5 Newton 3.5 Newton respectively?
Answers
Answer:
Friction is a force that opposes two objects sliding against each other, and is a contact force like the normal force. While the normal force acts perpendicular to the flat surface, friction acts in a direction along the flat surface of an object.
:- Additional
The force of static friction can be calculated by taking the coefficient of friction between the two surfaces and multiplying it by the normal force that the surface is applying to the object. On a flat surface, the normal force is equal to the force of gravity acting down on the object.
Since ,according to question a body starts sliding on applying a force of 3 Newton. So, if we talk about the force 0.5 Newton 1 Newton and 2.5 Newton when these forces are applied on the body the body does not slide show in this case the frictional force is greater than applied force when the applied force is greater than or equal to three Newton then the blocks starts sliding it means that in the case of 3.5 Newton the force of less than the applied force due to which the body starts sliding.
