Since T= 2(m1*m2/m1+m2) g.
If we put the value of mass half.
So, the answer is [A].
If we put the value of mass half.
So, the answer is [A].

2T= (m'g+m"g).
Now 50% reduced from both:
2T* = .5(m'g+m"g) = .5X2T.
T* = .5T.
Now 50% reduced from both:
2T* = .5(m'g+m"g) = .5X2T.
T* = .5T.

Here, F or T is directly proportional to mass M, when M is reduced 50 % then Force tension is also reduced 50 % means half.

Tension is directly proportional to the mass of the body. If there is a certain amount of reduction in mass of the bodies then Tension (T) will also be reduced by the same amount. So it will be half.

Tension in both side of the string will be equal because tension is directly proportional to the body mass. If reduce 50% in mass then tension will be half and equal to both side.

From the formula.
T=Mg.
We know simply tension (T) is directly proportional to the mass of body (M). And hence 50 percent reduction in the mass reduces the same amount of tension in the string. Hence tension will be half.

Looking at the figure if mass is reduced equally on both sides irrespective of percentage, the tension reduces by the same amount. Simple logic.

If body is in equilibrium than it means weight = tension; as weight reduces to 50% of original. So it is obvious that tension becomes half.
