Figure 1 shows a computer monitor sitting on a desk and the desk rests on the surface of the earth. If the weight of the desk is the "action", what is its "reaction"? The upward normal force on the desk by the surface of the earth. The upward gravitational pull of the desk on the earth. The upward normal force on the monitor by the desk. The downward normal force on the surface of the earth by the desk. The downward normal force on the desk by the monitor. A block of mass is placed on an inclined surface. The incline makes an angle with respect to the horizontal. What are the magnitude and direction of the normal force exerted on the block by the incline? magnitude , direction: perpendicular to the incline surface magnitude , direction: perpendicular to the surface of the earth magnitude , direction: perpendicular to the surface of the earth magnitude , direction: perpendicular to the incline surface magnitude , direction: perpendicular to the incline surface
