## Homework Statement

## Homework Equations

Work Done=Force*Displacement in the direction of the force

## The Attempt at a Solution

I tried to solve the problem this way,

I wrote these equations for the two masses,

T-mg=ma......(i)

Mg-T=Ma.......(ii)

From (i)&(ii), T=[M(g-a)+m(a+g)]/2

and then I would multiply them with the displacement to get the net work done 0.

So this is how I solved it mathematically.

Can you please provide an intuitive explanation of why the net work done by tension would be zero?

I will be thankful for help!
