Solving Tension in Simple Pendulum at Centre Point

[ritwik06]

Homework Statement

A simple pendulum is oscillating. When it is at the centre, what is the value of tension in string?

Homework Equations

The tension= The weight= mg

Am i right? Please help!

Of course it is. :) You are damn right!

No, you are NOT correct.
At all times, the tension must provide the CENTRIPETAL ACCELERATION of the attached mass as well.

aldrino has a solid point! :)

oh yes. as well as the acceleration due to gravity. isn't it? now the force must be greater than mg.

Quite so!

Quite so!

Thanks a lot!
