WHAT IS WORK DONE BY THE TENSION IN THE STRING OF A SAMPLE PENDULUM???

The work done by tension on the string of a simple pendulum is always zero.
This is because the direction of tension is such that it always acts perpendicular to the displacement produced. So, as θ = 90o, Cosθ = 0 and so is the work done (work done being W = FsCosθ)
