Solution:
Maximum Friction force action on an object is μN.
Here μ=0.2 and Normal reaction force will be equal to applied force i.e 10 N.,
So, friction force is 0.2*10 = 2N
A horizontal force of 10 N is necessary to just hold a block stationary against a wall. The coefficient of friction between the block and the wall is 0.2. The weight of the block is
