Two boxes are placed on an inclined plane at angle a to the horizontal. The masses of the two boxes are m₁ and m2, and the coefficients of friction are µ₁ and μ2, such that μμ₂. What is the force with which the first box acts on the second box? Image size: S M L Ma α Select the correct answer Your (m₁ + m₂)² (µ₁ −μ₂) (g cos a)/(m₁ - m₂) Answer ○ (m₁ + m₂)² (μ₁ −μ₂) (g sina)/(m₁m₂) ○ (m₁ + m2)² (µ₁ − μ₂ cos α)g/(m₁m₂) O m₁m₂ (μ₁ −μ₂) (g cos a)/(m₁ + m₂) ○ (m² + m²) (μ₁ −μ₂) (g cos a)/(m₁ m2
