Homework Help: Find the tension in a string

  1. Jun 16, 2012 #1
    1. The problem statement, all variables and given/known data

    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.

    2. Relevant 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?
