my question is-a horizontal force of 10N 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? 4:53 pm i handled the question by applying this eqaution 10+Mg-0.2Mg=0 but not getting the answer just want to know where i was wrong

the part where u were wrong is that the normal force is not provided by gravity...rather it is provided by friction...so the equation actually comes out to be
10(0.2) โ€“ Mg=0
or
Mg=2N
