Because in M1 tension is always the same.

Because it is the same string; it's threaded through a (smooth) bead.

Smooth being the operative word - if it wasn't smooth, the tensions wouldn't be the same.

I'm sure the tensions will be different. Depends on the situation, do you have the markscheme?

Edit: OP are you asking about tension from AB and to BC?

They're not different. The bead is smooth.

Thanks, I just saw that it's smooth and fact that the question just says "tension".

Is the tension the same because the string is light as well?

No, the lightness just makes finding the weight of the bead easier, and you don't have to take moments into account, etc. The smoothness brings about the uniformity of tension, because the string can pass through the bead without any resistance.
