Three blocks are connected by massless strings on a frictionless inclined plane of 
as shown in the figure. A force of 
is applied upward along the incline to mass 
causing an upward motion of the blocks. What is the acceleration of the blocks? (Assume, acceleration due to gravity, 
)
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
The given situation is shown in the figure below,
For 
block.
For 
block
for 
block
Adding Eqs. (i), (ii) and (iii), we get
Hence, acceleration 
of block is 
.
