To find the tension in the rope, we need to analyze the forces acting on the block. Since the block is moving at constant velocity, the net force acting on it is zero.

 

Step 1: Identify the forces

1. Weight of the block ():

 

2. Components of the weight:

Parallel to the incline:

 

Perpendicular to the incline:

 

3. Normal force ():

The normal force is equal to the perpendicular component of the weight:

 

4. Frictional force ():
