A Block Is at Rest on a Rough Inclined Plane $\theta$

question 103

Multiple Choice

A block is at rest on a rough inclined plane and is connected to an object with the same mass as shown. The rope may be considered massless; and the pulley may be considered frictionless. The coefficient of static friction between the block and the plane is μs; and the coefficient of kinetic friction is μk.

-What is the magnitude of the static frictional force acting on the block?

• A)mg sin \(\theta\)
• B)mg cos \(\theta\)
• C)mg(1 - sin \(\theta\))
• D)mg(1 - cos \(\theta\))
• E)mg
