The question is not very clear.
Let us say that the cuboid-shaped wooden block is open on the right side face. Then there are some weights, which can be added to the block one by one. Then the total weight of the block is increased step by step.
Let us say that the wooden block is moved along the surface of the table in horizontal direction. Then the force required to move the block is equal to the static frictional force between the block and the table.
That is equal to F = μ m g
μ is the coefficient of friction between the block and table.
m is the total mass of block including weights in it
g = acceleration due to gravity of Earth = 10 m/s²
F is measured using the spring balance which is used to pull the block.
clearly, the force required is maximum, when m is maximum. ie., when 40 gm weight is put in the block.
let us say that the block is lifted vertically by hooking it to the spring balance. Then the force required to lift the block is equal to the weight of the block including the additional weights. Then this force is maximum when 40 gm weight is put in.
