Question

A heavy block is pulled across a rough surface. In case 1, the applied force and the surface are both horizontal. In case 2, the applied force is parallel to an inclined surface up which the block is pulled. If both applied forces are identical, which of the following is true?

		The frictional force in case 1 is greater than the frictional force in case 2
		The frictional force in case 2 is greater than the frictional force in case 1
		The frictional forces are identical in magnitude in both case 1 and case 2
		The frictional forces cannot be compared unless the angle of the incline is known
