A pushing force of magnitude 7.10 N acts on a box of weight 7.10 N at an angle 0 = 26.0 degrees below the horizontal as shown below. P W The box is sitting on a rough surface and remains at rest while the pushing force is applied. What is the magnitude of the normal force from the surface acting on the box? Give your answer in Newtons. Do not enter the units into the answer box. Assume all values are given to three significant figures of precision
