Question

As part of your daily exercises, you push against the wall with your hands. You apply a force $F$ at the angle shown in the diagram. (a) What is the magnitude of the normal force of the wall against your hands? Give your answer in terms of $F$ and $ heta$. $N = $ (b) If you now decrease the angle of the force by getting closer to the wall but do not change the magnitude of the pushing force, how will this affect the normal force? $circ$ The normal force will decrease. $circ$ The normal force will remain the same. $circ$ The normal force will increase. (c) If you move further away from the wall as you push with the same force, thus increasing the angle, how will this affect the normal force? $circ$ The normal force will decrease. $circ$ The normal force will remain the same. $circ$ The normal force will increase.
