Concept explainers
A block is at rest on an incline as shown below at right. A hand pushes vertically downward with a constant force. The block remains at rest on the incline.
c. Suppose that the hand were to push with a constant force directed as shown at right. The block remains at rest on the incline.
-
i. Is the magnitude of the net force on the block
greater than, less than, or
equal to the magnitude of the net force on the block in part a? Explain.
ii. Is the magnitude of the frictional force exerted on the block by the incline greater than, less than, or equal to the magnitude of the friction force exerted on the block by the incline in part a? Explain.
