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 µ 1 and µ 2 respectively -
A
If μ 1 > μ 2 , the blocks will always remain in contact
B
If μ 1 < μ 2 , the blocks will slide down with different accelerations
C
If μ 1 > μ 2 , the blocks will have a common acceleration 
( μ 1 + μ 2 ) g sin θ
( μ 1 + μ 2 ) g sin θ
D
If μ 1 < μ 2 , the blocks will have a common acceleration 
sin θ
sin θ
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, b, c)
If μ 1 > μ 2 then a 2 > a 1 both move with together. If μ 1 < μ 2 then a 1 > a 2 both move separately.
