Weightlessness is experienced when the normal force equals __________.

$\begin{align*}&\text{A block of mass }190kg\text{ rests on an incline of }33^{\circ}\&\text{It is also partially supported by a rope with a tension of }559.17N\&\text{What is the normal force acting on the block from the surface?}\&g=9.81\frac{m}{s^2}\end{align*}$

A book of mass 1kg is held to a vertical wall by a person's hand applying a 20N force directly toward the wall. The wall has a static friction coefficient of 0.3 and a kinetic friction coefficient of 0.2. With the book held at rest, what the is frictional force keeping the book from sliding down the wall?

$\begin{align*}&\text{A block of mass }267kg\text{ rests on an incline of }49^{\circ}\&\text{What is the normal force acting on the block from the surface?}\&g=9.81\frac{m}{s^2}\end{align*}$
