Net Force acting on block on incline

[TheFlemster]

Homework Statement

A 6.50 kg block is placed on an inclined surface. The coefficients of static and kinetic friction between the block and the surface are 0.685 and 0.485, respectively. The incline makes an angle of 18.8° relative to horizontal. The block is at rest and remains at rest. What is the magnitude of the net force that acts on the block?

Homework Equations

net Force, F = ma

The Attempt at a Solution

F = ma
F = mass * acceleration
F = mass * 0
net Force, F=0
