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,
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!
