Could someone please look at the problem below and see if i am on the right lines of solving it? I am finding the whole subject of circular motion hard to get my head around and therefore not 100% confident in my workings. I have also attached my free body diagram.

Calculate the tension in a 3m string attached to a 3kg bob that is moving in horizontal circles of 0.6m radius

Tanθ = Opposite/Hypotenuse

TCosθ = mg

θ = Tan-1 0.6/3

θ = 10.32°

TCosθ = mg

T = mg/Cosθ

T = (3Kg x 9.81) / Cos 10.32

## Homework Statement

Calculate the tension in a 3m string attached to a 3kg bob that is moving in horizontal circles of 0.6m radius

## Homework Equations

Tanθ = Opposite/Hypotenuse

TCosθ = mg

## The Attempt at a Solution

θ = Tan-1 0.6/3

θ = 10.32°

TCosθ = mg

T = mg/Cosθ

T = (3Kg x 9.81) / Cos 10.32

**T = 29.91 N**
