Centripetal Force

  1. Nov 24, 2005 #1
    Question 1
    A conical pendulum consists of a string of length 1.2 m and a bob of mass 0.41 kg. The string makes an angle of 21° with the vertical. Calculate the tension in the string, in N.
    iam not sure wat to do here if
    [tex] l\omega{}^2 = \frac{g}{\cos\phi}[/tex]
    then i use
    [tex] T=ml\omega{}^2[/tex] to get the force. is that the way to calculate the tension. Thanks in advance

    First draw a diagram. I think you will see the answer when you do that.

    (what would the tension be if it were straight down?)

    Tcos 0 = mg
