**1. Homework Statement**

Calculate the tension in a 5 m string attached to a 4 kg bob that is moving in horizontal circles of 0.6 m radius.

**2. Homework Equations**

**3. The Attempt at a Solution**

α= tan-1 0.6/5

= 7 degree

T cos α = m*g

T= m*g/cosα

T=4*9.8/0.12

T=326.6 N

I just want to check whether my working is correct or not.
