Question

What is the magnitude of the static friction force required to keep a 2.00 kg block resting on an inclined plane at an angle 25 degrees? 

If the angle was increased, such that the incline plane was steeper, would the magnitude of the static friction force required to hold the block at rest increase, decrease, or stay the same?

Expert Solution
Step 1

Given:- 

The mass of the block is m = 2.0 kg 

The block on the rest condition on an inclined plane at an angle θ=25° 

Find:- 

a) What is the magnitude of the static friction force?

b) If the angle was increased, such that the inclined plane was steeper, would the magnitude of the static friction force required to hold the block at rest increase, decrease, or stay the same?
