Transcribed Image Text:**Conceptual Question:**
The block below slides with constant velocity under the action of an applied force as shown. Given that there is friction, which statement is true?
(a) \( W = N, |\vec{F}_{\text{app}}| = |\vec{F}_{\text{fric}}| \).
(b) \( N > W, |\vec{F}_{\text{app}}| = |\vec{F}_{\text{fric}}| \).
(c) \( N > W, |\vec{F}_{\text{app}}| > |\vec{F}_{\text{fric}}| \).
(d) \( N < W, |\vec{F}_{\text{app}}| = |\vec{F}_{\text{fric}}| \).
(e) \( N < W, |\vec{F}_{\text{app}}| > |\vec{F}_{\text{fric}}| \).
(f) None of the above.
**Diagram Explanation:**
The diagram shows a block on a horizontal surface. An applied force (\(\vec{F}_{\text{app}}\)) is directed at an angle \(\theta\) below the horizontal plane towards the block. The applied force is responsible for moving the block. The frictional force (\(\vec{F}_{\text{fric}}\)) opposes this motion.
- \(W\) represents the weight of the block.
- \(N\) represents the normal force.
- The applied force has both a horizontal component (causing motion) and a vertical component (affecting the normal force).
Since the block moves at a constant velocity, the net force along the direction of motion is zero, meaning the forces are balanced in that direction. Additionally, vertical forces are balanced due to equilibrium.
