A body of mass 0.6 mg kg is whirled in a vertical circle making 5 revolutions in one second . If the radius of the circle is 1.4 m , find the tension in the string , when the body is (i) at the lower most of the circle point , (ii) at the top of the circle .

Explanation

To solve the problem, we need to find the tension in the string when the body is at the lowest point and at the highest point of the vertical circle. We will use the following steps:

### Given Data:
- Mass of the body, \( m = 0.6 \, \text{kg} \)
- Radius of the circle, \( r = 1.4 \, \text{m} \)
- Number of revolutions per second, \( n = 5 \)

### Step 1: Calculate the Angular Velocity
