The same heavy wooden block is dragged by a force F along a rough steel plate, as shown below for two possible situations. The magnitude of the acceleration is the same for the two situations; do not assume that the magnitude of F is the same. The magnitude of the frictional force in (ii), as compared with that in (i) is: Select one: O a. less for some angles and greater for others O b. less Oc. the same O d. greater O e. can be less or greater, depending on the magnitude of the applied force.
