Q:

What would happen if plane try to take off on conveyor belt?

A:

It depends on the direction of the conveyor belt!

 

If the conveyor belt and the plane are moving in the same direction, it's as if you added speed to the plane. The plane would have more air forced over the top of the wing, meaning that air will speed up and create lower pressure: Bernoulli's principle. This means the plane would have more lift and take off easier and faster.

However, if they're moving in opposite directions, it woud be subtracting velocity from the plane. There would be more drag, less lift. The plane would have a harder time getting off the ground.
