Question

The two blocks A and B of equal mass are initially in contact when released from rest on the inclined plane. The coefficients of friction between the inclined plane and A and B are μ₁ and μ₂ respectively.

(a) If μ₁ > μ₂, the blocks will always remain in contact. 

(b) If μ₁ < μ₂, the blocks will slide down with different accelerations. 

(c) If μ₁ > μ₂, the blocks will have a common acceleration 1/2 (μ₁ + μ₂)gsin θ.

(d) If μ₁ < μ₂, the blocks will have a common acceleration μ₁μ₂ / μ₁ + μ₂ sin θ.

Answer 1

Correct Answer is: (a, b)

The block with lower value of μ will tend to have greater acceleration down the slope.
