Solution

Solution Steps

Step 1: Identify the forces acting on the fan

The problem involves a fan on a scale blowing air upwards. We need to identify the forces acting on the fan.

Step 2: List the possible forces

The possible forces acting on the fan are:

Weight (W)
Normal force (N)
Tension (T)
Friction (f)
Drag (D)
Thrust (Th) / Applied (A)

Step 3: Determine the direction of each force

Weight (W): Acts downwards due to gravity.
Normal force (N): Acts upwards, perpendicular to the surface, balancing the weight.
Tension (T): Not applicable in this scenario as there is no string or rope.
Friction (f): Not applicable as there is no horizontal movement.
Drag (D): Not applicable as the fan is stationary.
Thrust (Th) / Applied (A): Acts upwards due to the fan blowing air.
