Two identical blocks are pulled along a rough surface as suggested in the figure. Which one of the following statements is false? A force of the same magnitude is needed to keep each block moving. The normal force exerted on the blocks by the surface is the same for both blocks. The coefficient of kinetic friction is the same in each case. The magnitude of the force of kinetic friction is greater for the block on the right. A force of the same magnitude was required to start each block moving.
