A block of mass 10 kg is resting on a horizontal floor. What is the force applied by the floor on the block? (Acceleration due to gravity g = 10 m/s2)
100 N
Given mass of the block, m = 10kg
Weight of block, W = mg = 100N
The block is applying a force of 100 N on the floor. According to the third law of motion, for every action, there is an equal and opposite reaction. So, the floor will apply a force of 100 N on the block in the upward direction.
