If the tension is being half on moving downwards then surely be double on upward.

After compairing both situations.
The acceleration = g/3.
The acceleration = g/3.

@Gurdeep @Gaurav.
Problem shows that;
m(g-a) = m(g+a)/2.
Problem shows that;
m(g-a) = m(g+a)/2.

g/3 if the acceleration is constant otherwise, option D.

Acceleration will be constant which is g=9.81 mm/s^2

@Gurdeep.
You are right, the answer is option D.
You are right, the answer is option D.

2m(g-a)=m(g+a)
2g-2a=g+a
g=3a
a=g/3
2g-2a=g+a
g=3a
a=g/3

a = g/3.
The right answer is B.
The right answer is B.
