because the maximum friction force that can be provided between the two blocks becomes 0.1*800= 80N, and we only need 20N for support, so it's fine..?PeroK said:
Looks right. You might want to add why block P does not slide.
Yes, it was fairly obvious from the numbers that the maximum force was needed for Q (as it is much heavier). But, it does no harm to show the calculation for P as well.nafisanazlee said:

The minimum force required to keep two blocks from not falling is the minimum amount of force needed to counteract the force of gravity and prevent the blocks from falling.
The minimum force required to keep two blocks from not falling is calculated by using the formula F = mg, where F is the force, m is the mass of the blocks, and g is the acceleration due to gravity.
The factors that can affect the minimum force required to keep two blocks from not falling include the mass of the blocks, the surface area of contact between the blocks and the surface they are resting on, and the angle at which the blocks are positioned.
Yes, the minimum force required to keep two blocks from not falling can be greater than the force of gravity. This is because the minimum force required is dependent on the mass and other factors, whereas the force of gravity remains constant.
The minimum force required to keep two blocks from not falling can be increased by increasing the mass of the blocks, increasing the surface area of contact between the blocks and the surface they are resting on, and increasing the angle at which the blocks are positioned.
