Question

What is the work done by tension in the string of simple pendulum?

Answer 1

Answer:

Hey dude... 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).

Hope it helps you... ✌
