when is tension in a rope equal at every point ??
when there is no friction in the pulley
when the ropes radius in less than 1000 mm
when nothing hangs from the rope
when there is no mass in the rope

there is no tension in the rope when it is massless.....it is because if we consider it to have mass, then at every point from the bottom of the rope, the overall weight changes because in our process to find tension we will have to add the mass 'm' and the mass of the part of the rope on which we need to find the tension and multiply it with 'g'(acc. due to gravity)....(in this particular case)......
