are normal reaction and tension conservative ?

[Chetan <chetanreddy@ETH.NET>]

I think it depends on what forces are causing the normal reaction and
tension(like when two masses are hanging on the opposite sides of a pulley
then the tension in th rope is due to gravity which is a conservative force
and so the tension is conservative).

Is this right?
