In figure, a body 
of mass 
slides on plane inclined at angle 
to the horizontal and 
is the coefficient of friction between A and the plane. A is connected by a light string passing over a frictionless pulley to another body B, also of mass m, sliding on a frictionless plane inclined at an angle 
to the horizontal Which of the following statements are true?
A
A will never move up the plane
B
A will just start moving up the plane when 
C
For A to move up the plane, 
must always be greater than 
must always be greater than
D
B will always slide down with constant speed
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(b, c)
Let A moves up the plane frictional force on A will be downward as shown.
When A just starts moving up
When A moves upwards
