Two blocks made of different materials, connected by a string, slide down a 30° inclined plane . Block A has mass 8kg, and the coefficient of static friction between Block A and the incline is 0.35. Block B has mass 4kg, and the coefficient of friction between block B and the plane is 0.25. After the blocks are released, find the tension in the cord.

• A. 1.23 N
• B. 2.21 N
