Question
Two masses M1 and M2 are attached to the ends of a light string which passes over a massless pulley attached to the top of a double inclined smooth plane of angles of inclination α and β. If M2 > M1 and β > α then the acceleration of block M2 down the inclined will be :
Options
A.
B.
C.
D.zero
Solution
M2 g sinα − T = M2a [Newton′s II law for M2]
T − M1g sinβ = M1a [Newton′s II law for M1]
By adding both equations
a =
