What is the Tension in a Rotating String?

[Rohaaan]

Homework Statement

A body of mass 1.00kg is tied to a string and rotates on a horizontal, frictionless table. If the length of the string is 40cm and the speed of revolution is 2.0m/s, find the tension of the string.

Homework Equations

a = v^2 / r

f = ma

v = 2∏rf

Thanks :)

Care to show us your attempts. ;)

What are the forces acting on the body?

I would attempt it, but I don't really know how to go about it. :(

Can you tell what forces are acting on the body?
