Quick comprehension check

A 5 kg box is placed on an inclined plane angled at 20°. The coefficient of static friction between the box and the plane is 0.3. Will the box slide down the incline? Show your calculations and explain your reasoning. A block is placed on an inclined plane. The component of gravity acting parallel to the incline is calculated to be 10 N. The force of static friction is calculated to be 8 N. Will the block move? If so, in what direction? Explain your reasoning.
