Two blocks m 1 = 4kg and m 2 = 2kg, connected by a weightless rod on a plane having inclination of 37 
. The coefficients of dynamic friction of m 1 and m 2 with the inclined plane are µ= 0.25. Then the common acceleration of the two blocks and the tension in the rod are
Text Solution
Verified by ExpertsThe correct answer is:
A
Apply newton’s law for system of m 1 and m 2
a = 
= g [sin37º – µcos37º]
Now apply newton’s law for M 1
m 1 g sin37º + T – µm 1 gcos37º = m 1 a = m 1 g [sin37º – µcos37º]
T = 0 and a = 4m/sec2
