Verified Answer
Two men of unequal masses hold on to the two sections of a light rope ...
Here m2>m1
If lighter man is stationary,
Vertical force on m1
T−m1g=0
⇒T=m1g
Vertical force on m2
m2a=T−m2g=m1g−m2g
a= m1/ m2 g−g
since m1/ m2<1, so in this case, a is negative. thus the heavier man of mass m2 is sliding down.
If heavier man is stationary,
Vertical force on m2=T−m2g=0
⇒T=m2g
Vertical force on m1=m1a=T−m1g=m2g−m1g
a= m2/ m1 g−g
since m2>m1 so in this case, a is positive . Thus the lighter man will climb up with some acceleration.
From the above two cases we can say that they will move with the same acceleration over the pulley but in the opposite direction.
Ans:(A),(B),(D)

Two men of unequal masses hold on to the two sections of a light rope ...
From the figure,the two men move with acceleration of the same magnitude in opposite directions.
Let m1>m2
T= tension in the rope
If m2 is stationary then T=m2g
Therefore m1 must slide down with some acceleration.
If m1 is stationary then T=m1g
Therefore m2 must slide up with some acceleration.
If m1g>T>m2g, m1 can move down and m2 can move up.
It is possible when heavier man will slide with some acceleration, the lighter man will remain stationary and also when the lighter man climbs with some acceleration, the heavier man is stationary because they have equal and opposite acceleration.
