Answer:
The force of friction is 2 N. The object isn't moving.
Explanation:
The frictional force on a object is given by it's normal force multiplied by the coefficient of static friction between the object and the surface. In this case since the surface is horizontal, the normal force is equal to the weight of the block with the oposite direction. So we have:
F_friction = 0.5*N = 0.5*(10) = 5 N
Since the friction force is oposite to force that's acting on the block and it's greater than that force, the object won't move and the real force will be the same as the applied force. So we have:
F_friction = 2 N
The magnitude of the friction force is 2 N. The object should not be moved.
What is friction force?
The friction force should be provided by multiplying the static friction coefficient that lies between the project and the surface. When the surface should be considered as the horizontal so the normal force should be equivalent to the block weightage and the same should be in opposite direction.
So, the friction force is
= 0.5*N = 0.5*(10)
= 5 N
The friction force should be the opposite that acted on the block also it is more than the force due to this there is no movement of the object. Moreover, the real force should be same.
So, here the friction force should be 2N
